Okay so my last period was on the 8th and ended on the 12th (that was actually a week late from before, and was so light I didn't cramp and the only time there was a lot of blood was when I was having sex with my husband) so now I'm 2 days late, now for 3 days I've had really bad cramps and super sore nipples now they have stop, the only thing I get is random slight cramps that last for a few minutes then stop there not painful but there noticeable, so now I'm so confused on what the heck is going on, at first I thought I was pregnant but took a test and was negative so I'm guessing I might be due to stress or cause I'm just getting over a cold I don't know for sure.
