I've missed my periods. It's a little more than been a week since my period due. I'm having pregnancy scare as i'm sexually active. Although yesterday I checked through the pregnancy test kit which came out to be negative. Is it too early to test for pregnancy? Or there might be some other reason? Also, I popped one ipill (morning pill) approximately 2 months ago after which my next period was also a little delayed but this time the delay is more than before. I haven't got my periods yet also but i'm having sustaining abdomen cramps since last 2-3 days and slightly nipples hurting although there's no sign of periods yet.
