I find out tomorrow.. I went to the doctor and got blood work done.. I will let you know.

I am going through the same stuff.. I am 12 days late on my period.. took two pergnancy tests,both came out negative. I have had cramps and lower back pains for the last couples days and I was never this late on my period before. I been very emotional lately. I'm very anxious and scared. So if anyone finds out what it is. Please let me know.

With my first I was almost 3 months when I finally got a at home test to come back pos. the only reason I knew I was is because my doctor had done a blood test.
With my second I had a blood test done at 2 weeks because I was late. That test came back negative. 3wks later I took a at home test and that came back pos and also the test at the doctors the same day came back pos. I ended up losing that baby about a week after I found out I was pregnant.
Now I might be pregnant again. I am 2 weeks late. The doctor did a test and it came back negative and I did a home test and that came back negative. I plan on testing again this wkend and once every week until either I start or a test comes in pos.

I hope this helps. I too just a couple of days ago was wondering if I could possibly be pregnant. I have had low back pain and cramping like I was going to get my period. I tested 3 times, the first on the day of my missed period, second 3 days after my missed period and the third a week after my missed period and they were all negative. I figured my period was just going to come late but the low back pain and cramping continued with breast tenderness. I tested for the fourth time 12 days from my missed period and it came out very positive. I have never been late by more than a day before. I have been on birth control for about 6 years and just stopped two months ago. So I hope this info will help some of you out there. Good Luck!
