On March 28th i had unprotected sex (I know it’s bad i’ve started birth control now) with my boyfriend and he said he didnt remember finishing in me but that he wasn’t for sure. I got my next period normally which was on April 8 and i had it until the 15th.... Even though i got my period i’ve been getting bigger and lots of mood changes.... I’m a day late for my period now according to this app anddddd i don’t know what to do helpppp could i be? or am i worrying over nothing
