I am now 3 days late on my period. It’s almost been over a month since I had my last period. I have took 2 test and they were both very negative. I have been crampy on and off for the last 2 days. It last about 4 seconds then goes away for about 10 mins then again. It isn’t painful like a regular period. But my cervix are low and open. Could this just be my period is late or pregnancy and just not on pregnancy test yet? Ugh.
