Hey y'all. My last period was 26th march 2021 so that would make me 9weeks 5days into pregnancy but I went for a early scan yesterday and they said I'm 8weeks 2days. Also I had to have a internal scan as my womb is extremely tilted and was unable to see anything the normal way. Is it normal to be behind than what you thought? Also the heart beat was beating at 193bpm so would I be having a girl or boy?? Thanks y'all, here a picture of my little dot
