My beta quant level was 140 then it went down to 5 could i still be pregnant what's going on ? my progesterone is still good though... i'm confused..

See your doctor: Based on the data you provided, it appears as if you have lost your pregnancy. Make an appointment with your doctor to sort things out and come up with a plan.

Unlikely pregnant: Unfortunately a beta quant level that is falling from 140 to 5 is consistent with a pregnancy that is not going to continue. You can have a normal Progesterone level and still have a pregnancy that doesn't progress.
