Pregnant despite three neg tests?

[jamie_ky]

My partner and I are trying to conceive, and are wondering if I could still be pregnant even after three negative results?
My last period was jan 21 '08, and I average a 33, to 35 day cycle. I used an ovulation predictor which said I ovulated on the 8th. We inseminated on the 9th.
We used to home pregnancy tests, the first on feb 25th, the second on March 3rd. Both said negative.
I went into an Alternatives pregnancy center and also received a negative urine test.
I have some pregnancy symptoms like: nausea, fatigue, and vaginal discharge.
I am 11 days late today, which would make day 45 of this cycle. That seems quite excessive to me. Could I simply just not have enough hCG to be detected? And If that's true, will that cause an inevitable miscarriage?

Please help.
Thank you, Jamie and Ky

I had a similar experience last month.  I am going to share mine, but first let me tell you that I have read else where that it is possible to be pregnant and not test positive on a urine test!  

Hubby and I are trying to conceive are 1st.  I went off birthcontrol in November and had regular cycle in december.  My cycles are typically 32-35 days.  January came and nothing.  I should have started at the latest Janurary 31.  I had pregnancy like symptomst too.  Nausea, fatigue, high temps, and such.  The weird thing was with me, I had Period like cramps all throughout the time my period was MIA.  Then two weeks later (it would have been cycle dayt #50) my period came.  It was typical period, except the fact it was late.  However I am confused about the consistent cramping throughout the 2 weeks prior to AF arriving.  

Just thought I'd let you know my personal experience and I do hope that your story turns out differently.  Hope this helps!
