KIND OF LENGTHY RANT‼️‼️

Recently I’ve started intermittent fasting (IF). I read where women says that the IF messes with their periods rather good or bad. Ok, well I’m On month 5 of IF & My periods has been normally up until THIS month! I got my period TUES. (June4) normally i spot then bleed bleed bleed! BUt this month NOTHING but spotting ONLY when i wipe. Normally i wear a tampon. But I’ve only worn pads this time & absolutely no blood on the pad. Only time o see blood is when i wipe myself & its a dark brown color.

So I’m kinda concerned is it a possibility of pregnancy? Or the fasting effected my cycle? PLZ. Help!
