Morning. I want to ask. I had an irregular period, and now I am pregnant for an estimated 12 weeks but after the preksa doctor USG said the size of the fetus did not match the age of the fetus. Does irregular menstruation can affect the calculation of the age of the fetus can be wrong. Please answer. Thank you.

1 Answer:

Good morning, thanks for asking at HealthReplies.com. The size of the fetus is not affected by your menstrual cycle. You could have regular menstruation, but the potential for the size of the fetus does not match still exists. Conversely, your period may be irregular, but your fetus is normal. So if the purpose of your question is whether menstrual irregularities directly affect the incompatibility of fetal age with the estimated age of the womb, the effect is not there.


But if you mean more on calculating the estimated pregnancy, then there could be differences. Because to be able to estimate the gestational age, it takes certainty about when your HPHT / HPMT (First Day of Menstruation / Last Menstruation). If your period is irregular, there could be an error in determining the HPMT and this makes the estimated age of your pregnancy does not match the results of an ultrasound examination conducted by an obstetrician.


To ensure this, you can see from some of your backward ultrasound examination. If it has been appropriate and only now that is not appropriate, and the mismatch is more than 2 weeks, then there may be certain abnormalities experienced by your fetus until he is greater or smaller than the estimated gestational age. But if all this time is indeed not appropriate, it could be that the HPMT calculation has been wrong from the start. If only the wrong count, no problem and use the gestational age obtained from the latest ultrasound examination.


If this is your first examination, you should see the progress in the future. Your obstetrician will determine in some of these examinations whether there is an abnormality or not and treated according to the abnormality. Meanwhile, do not need to worry too much, limit physical activity, avoid smoking, coffee, and alcohol, do not consume drugs without doctor's advice, multiply the consumption of fruits and vegetables, make sure your food is cooked, and regularly consult a gynecologist. So, hopefully answering your question.
