Delayed in menstraution by three months. I haven't had an irregular period for more than half a year. So it's not odd for me. I'm 22 years old. What troubles me is the changes in the physique of my stomach. I am overweight (5'4 - 220lbs) so my stomach is quite out there. I didn't gain all this weight until five months ago. Although I think it's from the binge drinking I've done over the summer. Although I've had a few sexual encounters, They were very much protected. I've taken 6 pregnancy tests in the past couple of months. A week, if not more, after the other. And they all came out negative. I spotted once last month and once yesterday. That usually tells me that my menstraution is upon arrival but I have not yet gotten it. Any suggestions?
