- Subtract 3 months from start of last menstrual period
- Add one year
- Add seven days

This assumes a 28-day cycle. As this expectant mother normally has a 30-day cycle, some sources/textbooks indicate you should add or subtract the difference. In this case, 30 - 28 = 2, so you add 2 to get the EDD.

However, remember that the EDD is still advisory. It can be influenced by several factors including how regular a woman's periods are, ethnicity, weight, parity. Source: https://dx.doi.org/10.1111/ajo.13253
