i have one,
Preg 1- missed miscarriage- with my tilted uterus it was hard for them to see anything so they had to do transvaginal , baby was measuring week behind, but i ended up miscarrying a few weeks later. There was no growth in the scan the week after
Preg 2- i had a scan when i thought i was 6w 5 d, but they measured it a few days behind- but i didnt get transvaginal, they could see baby ok and there was a heartbeat. I had another scan a month later, but i was measuring a week ahead- so i think they got the early scan dates wrong- im not 100% sure on when i ovulated.
But anyway i think tilted uterus can make early scans quite inaccurate so fingers crossed for you xxx
