So me and my boyfriend had unprotected sex on the 4th of August (I had just finished my period) and even though he pulled out, we decided to get morning after pill the next day. A week later (10 Aug), I started to bleed again, thought it was just spotting but turns out to be quite heavy as if I got my period again. I understand that the pill caused my cycle to be irregular, but If I haven't taken the pill, I should've gotten my period a week ago. Should I be worried? We did have another unprotected sex (he pulled out though) a few days after my second period last month but didn't take the morning after pill again after which now I regret...

White discharge but no other PMS signs like normally (e.g. breast tenderness)
