How to calculate pregnancy after miscarriage without period

Calculating pregnancy after a miscarriage without a period can be a bit challenging, as the menstrual cycle may be disrupted following the loss of a pregnancy. However, there are a few methods that can help estimate the due date of a subsequent pregnancy.

Ovulation tracking

Ovulation can be tracked by monitoring basal body temperature, and cervical mucus, or using ovulation predictor kits. Once ovulation has been confirmed, it is possible to calculate the estimated due date based on the average length of a menstrual cycle (28 days).


A pelvic ultrasound can be performed to determine the size of the gestational sac and estimate the due date.

Hormonal levels

Blood tests can measure levels of human chorionic gonadotropin (hCG), which is produced during pregnancy. The rise of hCG levels can help determine the due date of the pregnancy.

It is important to note that these methods are not always accurate, especially in the early stages of pregnancy, and it is recommended to confirm due dates with regular prenatal check-ups and ultrasound scans.

Additionally, it is important to seek medical advice before trying to conceive after a miscarriage, as there may be underlying health conditions that need to be addressed. Your healthcare provider can also provide guidance on how to optimize your chances of having a healthy pregnancy.

In conclusion, calculating pregnancy after a miscarriage without a period can be done through ovulation tracking, ultrasound, or hormonal levels, but it is important to seek medical advice and have regular prenatal check-ups to confirm due dates.
