I have not yet received my period. I had sex on the 22nd of July and my last period started on the 5th of July. I bled after having sex but only a little. On the first of August I noticed brown spotted discharge and on the 12th I noticed it again until yesterday I bled only a little and today brown along with pains in my stomach and back. I am really confused as to why this is happening. We used a condom during intercourse and he did not release anything until he withdrew so please help me.
