So, I exercise everyday. I didn't exercise for 2 days tho, the day before yesterday and before that, because I had started my period (2 days late bc I took Plan B). I did exercise yesterday. Also, I've been sucking in a lot, I guess because I am paranoid that there is a baby bump even though I know it would be too soon for it to show, I am still paranoid. Along with that, I have been totally stressed out from my whole situation. Now my stomach hurts (not too much tbh just a little), would it be from exercise, sucking in, stress, or plan B? should I be worried?
