How to track ovulation days?

I have a quick question for you guys...
How much time actually passes before you can figure out the exact day conception happened—and what's the best way to go about it? To be specific, if a girl was with two different guys about 10 days apart, is there any way to tell which one it was? This is kind of urgent, please! Thanks!

If my memory serves me right, conception is typically calculated as being two weeks from the start of the last period, though actual conception can occur up to seven days after that—roughly day 21 of the cycle.🤔 ....

It’s not really a set-in-stone rule, is it? I mean, I know most people just calculate everything based on when ovulation happens, but I was kind of wondering if there might be some specific medical method or test—I don't even know what else to call it—to figure it out more precisely...

As far as I know, ovulation typically occurs somewhere between day 10 and day 14 of the cycle, counting from the start of the last period.🤔...

Of course, there's always the possibility of an early ovulation occurring...

You can also estimate the date of conception by measuring fetal size via ultrasound, though even that is just a rough approximation.

If the core issue is determining paternity—given that you mentioned she was with two different men within a ten-day window—the only foolproof method is a DNA test or a blood test to establish biological fatherhood once and for all.

Peter Myers29 said:If the core issue is paternity—since you mentioned she was seeing two different guys within a ten-day window—then honestly, there's no shortcut. You just have to get a blood test or a DNA test to figure out who the biological father actually is.

Yeah, definitely check back in nine months and let us know how it all turned out. 🤣

Megan Reed said:Sure, just check back in about nine months. 🤣

If you don't have anything constructive to add to the discussion, it's better to stay quiet. Anyone can tear down someone else's point; it takes very little effort.

Peter Myers29 said:If you don't have anything intelligent to contribute to this discussion, you’re better off staying quiet. Any idiot can tear someone else's post apart like that.

Get lost. 🙄 I’ll comment on whatever I want, wherever I want, and whenever the mood strikes me. Besides, we already have one massive headache to deal with right now; don't go creating another one for me. And by the way, if you hadn't noticed, I actually agreed with you there—for once. 😬

Hey everyone, let's please try not to get into these heated arguments—this is actually a pretty serious matter we're dealing with here

I think it’s possible to test fragments of the placenta or tissue containing DNA traces, but I’m not entirely certain... and honestly, it feels like those tests are usually done during the earlier months.

Don't hold me to that, though—I could be wrong. You might want to run it by your OB-GYN just to be safe.

Well... here's my take: first thing that pops into my head is you should probably go see a gynecologist.

Adam Taylor7 said:Look, everyone, let's stop bickering. This is actually a serious matter.

I am being serious. You just haven't clarified if this is about establishing paternity or simply calculating the due date.

As far as I know, paternity can be determined before birth via amniotic fluid testing—I believe the procedure is called amniocentesis—though it does carry significant risks... 🤔 ....

Generally speaking, it would be best to consult a specialist OB-GYN. They possess much more expertise than I do and will be able to provide definitive answers to these questions.

As for the arguing, some people clearly have inflated egos; they feel entitled to judge and critique others' posts based on their own arbitrary standards without adding anything meaningful to the conversation. And of course, when they're proven wrong, they immediately play the victim. Personally, I couldn't care less about the opinions of people like that.

The real issue here is that I’ve been seeing two different guys lately. With one of them, we used a condom, and then—as luck would have it—my period started right after we were together. I’m about 99% sure there’s nothing to worry about there, but with the other guy, we had unprotected sex about ten days later. My main concern is just... I really don't want to spend the next nine months living in total fear, you know? Usually, my cycle runs about five days late, but given how things went down this time, I’m feeling pretty anxious about it.😢

First things first: head to a local drugstore and pick up a pregnancy test.

If it comes back positive, make an appointment with your OB-GYN. From there, you can decide how you want to proceed.

Otherwise, pulling out is a notoriously unreliable method of protection.

Adam Taylor7 said:The real issue here is that these guys aren't even from the same background.

If you play it that way, you won't have any drama because you'll find out eventually. But if you aren't interested in waiting nine months to get an answer: go see an OB-GYN

😁@Peter Myers29: It looks like this whole situation doesn't bother you much, probably because she might just decide to keep the baby. 👍Not knowing who the father is isn't necessarily a crisis. But hold on—she might still claim she's going to terminate, and then she’ll be the one facing the music.

Peter Myers29 said:If I recall correctly, conception day is considered two weeks from your last period, though actual conception could happen up to 7 days later (up to day 21 after menstruation)... 🤔 ....

Everything you’ve just laid out is completely incorrect, ranging from what you consider a cycle, to the timing of ovulation, all the way to the window when conception can actually occur.

It's all wrong.

The first day of the cycle is officially the first day of your last period. In a standard 28-day cycle, ovulation typically happens on day 14, but the truth is, you never truly know the exact moment of ovulation until your next period arrives—then you look back 14 days to find it. Once ovulation occurs, the egg is viable for about 24 hours, but since sperm can survive for 48 or even 72 hours under ideal conditions, conception can happen if intercourse occurs three days before or even a day after ovulation.
If you had intercourse and then started your period just two days later, there is an extremely high probability that you aren't pregnant from that instance. If you had another encounter 10 days later, well, that depends entirely on how you are counting those ten days and how long your period lasts.

Peter, periods don't last the same amount of time for every woman.
Please, do take some time to read up on this so you aren't spreading misinformation; someone might actually listen to you, and then you'll have to live with that weight on your conscience... or perhaps you won't.😉

Really? 🤔 If memory serves, I believe I mentioned earlier that everything I said should be double-checked. I’m certainly no expert in this field, and I'm far from infallible. What I shared was mostly based on what I remember from freshman year of high school—which was about ten years ago. So, there it is.

silverraven95 said:Everything you just wrote is completely incorrect. From how you define a cycle to when ovulation happens and the window for conception.

It's all wrong.

The first day of your cycle is the first day of your last period. For a regular 28-day cycle, ovulation typically occurs around day 14, though you can never know the exact timing beforehand—you only know once your next period arrives that ovulation happened 14 days prior. An egg is viable for about 24 hours after ovulation, but since sperm can live for 48 to 72 hours under ideal conditions, conception can happen if intercourse occurs up to three days before or a day after ovulation.
If you had sex and then started your period two days later, there is a very high chance you aren't pregnant from that encounter. If you had sex again 10 days later, it depends entirely on how you are counting those ten days and how long your period lasts.

Peter Myers29, menstrual cycles don't last the same amount of time for every woman.
Do some reading on this; don't spread misinformation. Someone might take your advice, and you'll have to live with that. Or maybe you won't.😉

👍 👍 👍

I absolutely agree!

I don't know why, call me stupid, but when my washing machine breaks, I call a repairman, not a random person off the street.😈

Because a random person isn't qualified to fix an appliance. It’s only when health is on the line—which is clearly the case here—that suddenly everyone thinks they're more of an expert than a doctor. 🙂

It's actually pretty easy to nail down how old the embryo is using an ultrasound

Period finally arrived!!!!!!!!!🙏 thank God!!! 🙏 Seriously though—thanks so much for carving out a little bit of time to hang out with me!🙂

Don't mention it... 👋 ..... just try to be a little more careful moving forward. 😁
