A member asked:

Can a blood test confirm pregnancy even if a woman has low hcg at 3 and a half weeks after sex?

4 doctors weighed in across 2 answers

An HCG greater than 5 is a positive pregnancy, even if it is a low number. It will rise rapidly if a pregnancy is normal. Three and a half weeks after sex the test should be positive.

Dr Duvivier and another doctor agreed

HCG level in serum is a blood test and the result you provided is not consistent with pregnancy.
