I am 3 days late on my period. I have alot of the early signs of pregnancy like...nausea, breast tenderness, cramps that resemble the cramps that I usually get prior to my period, frequent urination, and fatigue. I took a pregnancy test when I was just 2 days late, and it came out negative. The last time me and my husband had unprotected sex was about a week and a half to 2 weeks ago. Is there a chance that I could still be pregnant?
