Early ultrasound weeks off dating

If you do know the conception date, this is classed as day 14 and not day one.

If you have an irregular cycle, or if you've recently been taking the contraceptive pill, working out the date from your LMP isn't a very accurate method.

It's wonderful to see a little blob with a heartbeat that will become your baby. If you are unsure of the first day of your last period you will be offered a dating ultrasound when you are between 10 and 14 weeks pregnant.

I am naturally quite concerned that the baby has stopped developing.Last week I went in for my first ultrasound, and according to my LMP I should have been 7 weeks and 2 days into my pregnancy.However, I was very concerned when the technician told us the baby was only measuring at 5 weeks and 3 days, and there was no detectable heartbeat yet.A supplement of vitamin C may be useful as it aids the conversion of cholesterol to bile acids.Milk thistle extracts in capsules or tablets may also be beneficial, as may phosphatidylcholine (PC) - a purified extract from lecithin that acts as a powerful emulsifier.Ultrasounds are more accurate than using the LMP and, if the ultrasound date differs from your period dates, the ultrasound date will be used.
