I’ve have a transvaginal at 6weeks and 2 days because I thought I had a uti and was having a lot of back pain and they wanted to make sure my baby was in my uterus which the baby was but the heart rate was 88 beats per minute and I am currently 6 weeks and 4 days now but I don’t wanna worry to much because I know they say 90 and up is normal and my first try I had a miscarriage so I’m making progress and trying not to worry but is that something to worry about or it’s normal ?
