Pregnancy Info HOME

My period is never usually late, but the last time I had it was on the 15th of November! I have been trying to get pregnant, so I stopped taking my Depo shot in May of '07. I've taken about 3 pregnancy tests within the past week or so, 1 of which was a urine test at the doctor's office, and all came back negative. I'm concerned because my period has been regular since about July, and I'm pretty sure I'm not getting it this month, lol. Is it possible to be pregnant without showing any HcG hormone in my urine yet? Please help me!
