DH and I have been trying to get pregnant. I've been off my birth control pill since the end of July. Ever since then my periods have been regular, about 28 or 29 days. According to my calculations I should have started my TOTM this past Friday but never did. On Saturday I decided to take a pregnancy test and it showed I was not. However yesterday I decided to try the test again, because I am impatient, and it still shows that I am not pregnant. Is it possible that the pregnancy hormone level has not increased enough to register on the pregnancy test. I am probably just jumping the gun. Thanks for an answers you may have.
