Okay so i started taking the combination birth control in February. Ive always had an alarm on my phone to remind me to take it and I've mostly been really good about taking it. My intention wasn't to have sex, but what ended up happening was I came home for the summer from college and my best friend (who is a guy) and I started hanging out again. We've always joked around about dating and having sex together just to get it over with so we won't die virgins (an inside joke between us), but we've both came to the conclusion (after multiple make out sessions) that maybe it wouldnt be a bad idea. So after fooling around a bit, we ended up having sex on tuesday morning (July 3rd). It was great and a lot of fun. We both enjoyed it, but what's worrying me is that he came inside me. I do struggle with anxiety so I naturally overthink and flip shit, so I start thinking, "oh dear god, what if im pregnant?" So I take my BC at 3:00 pm and I had already started the 2nd week of the pack. Problem is that I've read that if you throw up or have diarrhoea one day that counts as a missed pill. Now, I ate pineapple like 2 days prior and since pineapple is a detoxifier, I spent a decent time in the bathroom with a slight case of diarrhea, but nothing serious. Then the next day (July 2nd) I come home from work and decide to take a nap, but I forgot to take my pill at 3. By the time i got home it was already 4:45 ish. So i take it without a second thought. Then Tuesday morning happens and now I'm thinking about it so much that i even looked up the different ways my birth control couldve stopped working like leaving them in a hot car (which is somrthing im very paranoid about.)I've felt nauseous lately but when i eat it goes away. Nothing else is out of the ordinary. Istill have a week left of my pills for this month and my period should come around next week. But i cant help but wonder what is the likelihood.
