So the first day of my last period was August 1 and on August 9th my boyfriend was home on a slight break from work and we had unprotected sex. About a week and a half later i was noticing that my breasts were tender and looked kinda swollen, i was breaking out on my face (that's usual for me before an expected period though), i was nauseous here and there, i was irritable and sometimes i felt like i was going to cry over the strangest things, i was urinating a lot and i was bloated a little. I was apparently supposed to ovulate on August 15th and get my period on August 29th. I had experienced some brownish discharge about a week after the sex but i didn't think much of it until i was a day late then after that i was mainly just spotting. I did have some light period like bleeding for like two hours one night then i was back to spotting and all that lasted four days. I typically have heavy 5 to 6 day periods and this was a light four day "period". I have been having headaches almost everyday now, nausea but no vomiting, bloating, mood swings, increased appetite but when i go to eat i don't really find anything appetizing. My breasts still look swollen but they aren't as tender as before. My nipples look darker and i have these bumps around my nipples but inside my areolas. I took a pregnancy test and it was negative but i'm still not convinced because i have NEVER experienced anything like this.
