its a possibility..slim, but it is a chance
On the first day of your period, it's pretty much impossible. The follicle and egg would have had no time to grow since your previous cycle. Had it been the last day of your period, there would have been a low chance, but not on the first day.
yeah it is possible but not common. and your only 2 days late. you asked if your pregnant or if its just being too stressed so it sounds to me like your under a lot of stress and stress can effect your period
no u cant get pregnant if u have sex on period days.
Itis pretty unlikely that you would have conceived on the 1st day of your period....most people ovulate around mid cycle, give or take a few days. If you are late for your period, try using a HPT...good luck
