Hi, i'm 22 with two kids. I got my menstrual cycle on Dec. 2 and lasted for five days. On the 8th I started my second birth control pack throughout the 20th and after that i dind't take anymore. On the 12, my husband and I had sex and he came in me. On the 26th, I started bleeding then it turned brown and on the third day it stopped. On the 31st, we were sexually active again and I started bleeding again just for couple of hours then it turned brown and stopped on the third day. What can be happening with me can it be my period ir could i have gotten pregnant?
