Okay, so my period was suppose to start on the 7th, and it hasn't yet. I tested on the 8 and it came back negative. It's been 7 days late and I don't know whether I should test again or just wait to see if my periods just goingn to start late. I've been getting headaches, feeling nacious, craving and not craving. Moody. So I don't know what's going on. This happened 2 months ago minus the symptoms and my period just ended up coming late. This is the longest it's taken though it usually starts about 2 or 3 days after my scheduled period. What should I do????
