Hi, I too have a retroverted uterus. As I have had very erratic periods for some time, I could not give a LMP date and so had to have a dating scan. When the ultrasound was carried out the radiographer could not pick up anything at all, due to the position of my womb. This was obviously very worrying for me, and I feared the worst. However i then had an internal scan, and my little bean (and its heartbeat

) could be seen immediately and clearly.
I was dated at 7 weeks and 1 day from that scan, but was confused as to how they could be so precise without a LMP date. When I got home I realised that this date must be wrong as I know I didn't have sex around that time. ( I only usually see my partner at weekends) Therefore I estimate that am approx 3/4 days either side of that date.
The radiographer also said that my due date could be altered at my 12 week scan, which is on the 18th April.
I can't wait for my next scan and will be interested to see how clear it is, or whether my dates do change.
Keep us updated with your progress too hun,
xxxxx
