Hi everyone. Im 20 and ive had my period since I was 10. My ex husband and I got together when I was 18. Up until him and I started trying for a baby my period was like clock work...well it started to get irregular. So id sometimes have it every 4 months, 6 months or something in between. Well we started the divorce process two months ago and a few days later we hooked up. Not using any protection and he came in me. Well I then bleed for 4 days about a week later. Then 4ish weeks later I am now bleeding. It's light brown and its been 3 days. So I'm not sure if my period its fixing itself or off I could be pregnant. I've been moody and I've randomly thrown up 3 times and gotten nauseas about 7ish times. I've gained about 4lbs in my belly. So I don't know if this sounds like period crappyness or pregnancy stuff. I just don't know who to ask.
