New pregnancy or miscarriage hormones

Ericka

Had a miscarriage in the middle of June.. stop bleeding around the 5th of July. Did not get my cycle like I did last July when I had a miscarriage so I decided to take a pregnancy test and it came back positive.(I'm nervous and scared) Had sex three times this month I'm assuming if I did get pregnant it had to be from the first time but idk. Anyone have experience with pregnancy after miscarriage so early
