I had my last period at the begining of December, I had some light spotting on Jan. 9th and 10th along with cramping. The cramping still comes and goes at times. i have taken 4 pregnancy test but they all come up negative. I have heart burn off and on, tired alot of the time, i feel the same way i did when i was pregnant with my daughter. I am worried that I am this late and have had 4 neg test that something is seriously wrong with me. Have any of you ever had anything like this happen to you before?? I'm really freaked out, please help!!
