ASSHOLE DOCTORS

I had a misscarriage in june and they did an US Both ways, they said they seen nothing in me anymore that the gestational sac had evacuated and that once i got home i would have passed everything. i chose not to have a follow up with my obgyn since i never felt good with that doctor and two weeks after that i took a pregnancy test and came out negative, my first period didn't come until july 24 andasted about 10 days which seemed normal for after a misscarriage. according to glow i ovulated on the 6th of august and we BD and 10 days later i got a positive test and 2 days later i got another positive, i was suppose to be 5 weeks today, but i started spotting so I went to the ER and after waiting for about 4 hours they finally gave me my results and said that it was never a new pregnancy I just didn't release everything from my last one which didnt make sense to me.i just want opinions if maybe they could be wrong. also the ER doctor was so mean.
