Hi XXXXXXX

Thanks for your query.

Norethisterone is contraindicated in pregnancy.

There is high risk of fetal malformation and virilisation of female fetus. The potential risks are higher than benefits. There is a possible chance that the fotus can been harmed.

A pregnancy test should have been done before the medication was given to you.

I suggest that you consult your OBGYN about this, who should do an ultrasound and a repeat pregnancy test. The next course of action shall be determined after that.

Termination might be suggested to you depending on the ultrasound. Please dont panic as this is a most unfortunate incident.

Wish you Good Health.

Is there any chance that the baby could be ok and suffer no side effects?, even if slim?

Well,
its not possible to say that. There is always a chance that the baby will be ok. But the best time to look for fetal anomalies is between 16-22 weeks and only then can any congenital anomalies be located. As im sure you realise that very late in the pregnancy and if at all there is some anomaly, terminating the pregnancy at that stage is very distressing for the mother.I think you first need to find out if you have a viable pregnancy by consulting your Gynecologist. The first trimester is crucial.
