Reliability of ultrasound dating

The point of the scan is to work out how many weeks pregnant you are. Ectopic pregnancy and miscarriage: diagnosis and initial management CG 154. You may have calculated the length of your pregnancy from the first day of your last menstrual period (LMP). If you do know the conception date, this is counted as day 14, not day one.

This means that accurate dating reduces your chance of having your labour induced because your baby is thought to be overdue. Anyway, not exactly proud of this, but I was with 2 different men in a two week time period.One I didn't use protection with on Saturday April 7th (we have been very good friends for years, and it just happened on a night out drinking/dancing) and the other man I only went out with a few times, and when we slept together the following week (on Saturday April 14th), the condom broke.I can give an "estimate" but I really don't know because I never keep track.(Plus I have always been told that because of metabolic issues, and PCOS that it would be very hard for me to get pregnant).Ultrasound scans are considered to be the most cost-effective, accurate and safe methods for measurement of various fetal parts in pregnant women.
