So me and my bf had unprotected sex on my ovulation day but he didnt ya know 😅 but now I started what I thought to be my period a week early and only lasted 2 days. Day 1 was very heavy day 2 almost nonexistent now day 3 just very light pink and brown spotting. Been having a lot of pregnancy symptoms before this but pregnancy test come up negative but I'm only now coming up to the day when my period was supposed to arrive. What is going on?!?! Do I wait a little while and take a test or is it nothing to worry about?!
