Period is 10 days late. took test yesterday and it was neg. been under a lot of stress. severe cramping for a week. late last month. whats going on?

Stress itself: Can do wonders for messing up hormones--especially if you haven't been eating as much as you should. Your body is pretty smart. Also, unless your intention is to become a mom or catch something that could cause cancer or be there forever, i recommend condoms until all the cards are on the table. Repeat preg test in a week with first morning urine for best results.
