I know this is a very commonly asked question, but while I already have depression issues this scare has plummeted me into extreme anxiety. I'm 19 and I have a constant fear of being pregnant. It's usually irrational fears, but Ive never been as scared as now though. Now before I explain, I would like to say that I habe hashimotos and hypothyroidism, which before being diagnosed and taking medication my periods were unpredictable, but I never kept track. Hypothyroidism can cause this. I currently have a boyfriend, we've been together for a year and I've been keeping track of my periods for the most part. I usually will have very heavy painful periods at the end of each month around the 23, my symptoms start as early as the starting of the month around the 10th with swollen tender breasts and stop the night before my period. Then I cramp and have a heavy flow usually for around 5 Or 6 days. I had my period early on February, around the 18th or so. I went to my boyfriends house in the middle of March and stayed a whole week, I did not take my medication for hypothyroidism this whole time, during this time me and him "dry humped" me with some pretty thick tights on and him with his boxer briefs. I was very wet and it went through my tights and he only pre ejaculated, he never fully ejaculated. Which only left a sort of spot on his underwear, on a different day we also "dry humped" without pants, but he had a condom on and he didn't ejaculate around my vagina. I had no period symptoms this whole time, like I usually do. It is now the 25th of march and I'm having slight cramps and swolen/tender breasts and white discharge but just a tiny amount, but no period. I took a pregnancy test on the day I was supposed to have my period, and it came back negative. Please can someone tell me if there's a chance of me being pregnant? I'm so scared... sorry about the long question and story, I just want an accurate answer!
