okay so i had sex around 2 months ago. and it was two days before ovulation, well i was late for my period the next cycle by 4 days but it came and was brownish at first and then normal. now i’m at the time of my next period and yesterday i had a full red brownish color where i needed a tampon, today i only had a small amount of brown discharge. is this normal ? could i be pregnant? i also started the pill birth control on the sunday of my last period, could this be a side effect of the medicine ? or what ? i’m confused and scared. i’ve also been really bloated lately and the brown discharge stopped after yesterday now.
