Traditionally the last menstrual period has been used to date a pregnancy, but this may be highly inaccurate.

A simple formula is to take the first day of the menstrual period, subtract three months and add one week.

The heart beat of the embryo can be seen from 6 weeks onwards, therefore, the Early Pregnancy Baby Scan can be performed from 6 weeks 0 days – 10 weeks 6 days from the first day of your last menstrual period (LMP).

If your menstrual cycle is longer than 28 days it is advisable to wait until you are at least till 8 weeks from your LMP to confirm the viability of the embryo as you may not be as far as your dates suggest.
