I’ll be 25 in June… however starting back in March I was 2 weeks late for my period, had 1 positive pregnancy test however 2 blood tests were negative. In April I was a week and a half late…and now it’s may and I’m currently going on 5 days late and I took a pregnancy test this morning and it was negative…. Should I go see my doctor? My period has NEVER done this! No I’m not breastfeeding (I have a 16 month old) no I don’t have history of any PCOS or cysts, my period has always either been on time or a day late or a day early.
