Need advice asap!!:/

Tay • Hi my name is tay I have been engaged for 3 months and ttc baby #1 for two months now. We got pregnant back in november but lost it. We are now trying again for a miracle to happen.
I'm three days late I've had 3 faint positives I went to doctor yesterday negative test of course but she said they consider faint lines negative Then she gave me a blood test but gave me a qualitative blood test which obviously came out negative because it's the same as getting a pregnancy test at the store I needed a quantative because I think my hcg levels are to low to pick up I'm pissed off and don't know what to do... advice ladies??
