Thanks for the query.
Usually oral contraceptive pills
should not be used while being pregnant.
But there are well controlled studies over this.
As you used the pills for limited period there may not be much effect on the baby.
As baby is normal at present no need to worry.
But regular antenatal checkups and ultrasound
examinations are needed.
TIFFA scan is needed at around 20 weeks of pregnancy
to rule out anomalies.
