I haven't been on here lately, I've been trying to this pregnancy day by day ! Today was my second appointment I'm now 11 weeks & 3 days ! My babies heart beats were 150 & 160 !? The doctor made it seem so normal and good but I just have a weird feeling! I haven't gotten a chance to see them since last month! Should I be worried?? They say my next ultrasound is around 18wks 😩 I'm really considering finding another doctor office!!
