Has anyone ever gotten a false negative blood pregnancy test?

I know I'm not pregnant, but I am wondering if anyone has ever gotten a negative blood pregnancy test, but then they turned out to be pregnant.
What are your stories?? How far along were you in your pregnancy??
Thanks!!

Yes. My LMP was 7/16 and I went in for a blood test on 8/17 because I had not gotten my period and my hcg quant came back with a value of 1 miu/ml which means not pregnant. I went on with my life and started having sore boobs, fatigue, frequent urination, etc...around 8/26. I took an HPT on 9/4 and boom, pregnant. When I went in for my first OB appointment on 9/16 my doctor told me they were having problems with their machine giving off wrong numbers. I get my first ultrasound 10/14 so I can know exactly how far along I am, but according to him my blood test was a false negative. What's funny is my husband and I had an appointment with a fertility specialist set for Sept 1st but had to cancel it due to work conflicts. Looks like we don't need that anymore.

Yes, I did. I was one week past my period due date and I kept getting negative HPTs. So I went for the blood test. It as negative. I was sure of my dates and I am never late. I had been pregnant 3 times before and I just felt like I was. The Dr said she was 99% sure that I was not pregnant bc the blood tests are very accurate but had me come back in 2 days because your HCG (pregnancy hormone) level doubles every 2-3 days. Well that one was positive. I had an ultrasound and it was a very early pregnancy. The Dr said I must have ovulated and got pregnant late in my cycle and wasn't as far along as my last period suggested.
