Hi I'm really concerned with the fact that the month of March I did not get my period I took 2 HPT and both came back negative, I am bloated my breast are tender, I get nausous to certain smells and I get these sharp pains for 5 seconds and the it goes away. My last period was on Feb 28,2008, I had unprotected sex on Mar 8. Can someone please help me :confused:
