So I had a miscarriage in December and was pregnant before even receiving my first period after the miscarriage. My dr had me coming in every 2 days at the beginning to check hcg level and do ultrasound we did this for about 2 weeks straight because dr wanted to make sure it was a new pregnancy and that it wasn't just nothing left over so originally I was told my due date was 9/16 and that was from a ultrasound tech well my ob did a quick ultrasound 1 visit when I was 7 weeks and changed my due date to 9/22 from her measurements. Well I have had at least 4 ultrasound and baby has always been measuring around the 9/14-16 edd so I mentioned that to my ob n she tells me baby's can measure 3 weeks smaller or 3 weeks bigger it's not a concern or reason to change my date well the due date really don't matter to me because I know baby is going to come when he's ready I'm just thinking like couldn't that cause inaccurate info cause me to do testing later then normal or am I overthinking I really feel like my dr office only concern if Baby has a heartbeat or not and as long as they here it at the appts everything is fine to them.
