Some women wont test positive with a urine pregnancy test
its very rare but some ladires just dont test positive to a pregnancy until well into their first trimester, it does happen and you seem to be one of those ladies :)
I would go to a different doctor. That's really weird. Like the other girl said it usually means you're having a miscarriage but if they seen a heartbeat that can't be true. Schedule an appt with a different one n tell them you're situation n ask them to explain it.
I'm not sure. I asked my Dr and she skirted the issue.
I've never kept tract of hcg levels , but from my understanding, they'll double every 48 hrs or something, if your pregnant. if they don't or drop, then your not pregnant or having a miscarriage? that's what ive read.
hope everything turns out for the best ! x
