Need some help!

Please, if there is anyone out there who could offer some guidance—ideally someone with medical expertise—I am reaching out because I am in a state of absolute panic. I’ve had unprotected intercourse under some pretty difficult circumstances, specifically while under the influence of alcohol... and to make matters even more complicated, I have underlying health issues that cause my menstrual cycles to be incredibly irregular. I am just so overwhelmed with worry and stress right now. I honestly cannot believe I let myself get into this situation. If anyone is willing to help, please, reach out to me via private message. I need serious advice on what steps to take, especially considering the specific medications I am currently prescribed and my existing medical history (I can explain all those details privately). I haven't slept a single wink in a week... I am begging for some serious, helpful advice. Thank you.

Go see a gynecologist. You haven't slept in a week—did it seriously not cross your mind after one of those sleepless nights to just shower and go get checked out?

And what kind of advice are you even looking for? Emergency contraception doesn't work a week later. Your options are a pregnancy test, or if you are pregnant, dealing with birth or abortion, plus getting tested for STIs regardless of whether you're pregnant or not.
