this happened to me once before and when they ran the bloodwork it came up negative and turned out that i had a huge cyst on my ovary causing false positives. hopefully thats not your case and your BFP is a BIG BIG FAT POSITIVE!!!
i would go back because it looks like you have peeing on lots of sticks and they are all BFP's. Congrats.
they did a quantitative test at hospital!!!
Well I think you've got it figured! Congrats!!!!!! Yay!!
Did they do a pregnancy test or a beta hcg test?? I would call your doctor and ask them to do an hcg test because that will tell you for sure. I hope it is a true BFP but that was the only way for me to be sure that I was pregnant (even though I too got a big PREGNANT). Good luck to you!!
