Okay here's my case. I'm 19 yrs. old. My boyfriend and I had sex last June 2. It was my first time. When we did it I did not bled like they say on doing it for the first time. We used withdrawal, I sorta trusted him. In the morning, June 3 we did it again, same method. I saw him removed it before releasing sperm. Then June 4 I went to cr to poo, surprised to see that there is blood in the toilet, confused where did it came from (vagina/anus). Thinking it came from the vagina I thought it was my period. But after i washed, the blood disappeared till today. My cycle changes from 28 to 35. Everytime I will have my period I feel my breasts tender, but this time it went a little bigger. Is it an early symptom or not? I need answers thank you.
