My last periods was on October 3rd. My cycle changed from 30 days to 40 days cycle after I got married. I did a pregnancy test 3 days in a row and it was a faint line all those 3 days ( attached pic ). Went to a dr. and did beta test, the result was less than 1.2 HCG. It's confusing to see positive in the pregnancy test and blood test showing low HCG. I read in articles that there cannot be false positive and it is very rare. Why did my pregnancy result show positive all the 3 days and blood test show low hcg ? Please advise
