I've been on birth control for about 4 years. I've never experienced a irregular period even when I went off of it for 3 months. For the past 2 months I have been kind of bad at remembering to take it. I got my regular period on September 26, nothing different about it. On October 4th, I had unprotected sex 4 times with the guy I've been seeing then again on October 9, 3 times. The next Saturday, the 11th, I noticed pink stuff on the toilet paper after I wiped. I didn't think anything of it because it wasn't much. By Sunday I had enough pink discharge to stain my underwear. So I went on the internet and found out it could have been. I read about implantation bleeding. Monday morning, I noticed that this time I had brown discharge in my underwear. I also started having light cramps in my lower right side. By Monday afternoon, I had light bleeding. Nothing like my period, but enough for me to put a pad on. I figured that it was just my period until I read that implantation can be somewhat like you're period. My body has been feeling rather exhausted for the past week and I'm always extremely tired. I take atleast a 3 hour nap every day and go to bed early every night. I also notice I use the restroom more and my breasts are starting to get somewhat tendor. Most the time when I eat, I don't feel the best. Can someone help me?
