Open Question: 63 Days since last period? Negative Home Pregnancy Test!?

?. I was a young adult who is trying to pregnancy, but my body is strange. My deadline is to return 12 22. I missed a month, took home the test. They came back negative! Three of them! This is the second consecutive month, and the family I miss the test is still negative! I can not stress that I have changed my diet. I feel some symptoms, but few, I have heartburns dispensed, I would feel like throwing up a random. I also got my belly (womb area) there are also some low back pain and a number of significant emissions, random small cramps. But I throw it I brought all the families how to test negative. I will be for today's blood test, but may lead to what? Expressed appreciation for all the help! 3 NAT
