Hi there, I have understood your concern and I will suggest you the best possible treatment options.
First of all do not panic.
Duvadilan is not harmful in
pregnancy. It is used as a medicine to keep the
uterus relaxed. It exhibits its effects after 20 weeks of pregnancy.
There are very few evidences of its use in early pregnancy.
Instead , in my opinion please seek prescription support from your treating doctor for micronized natural
progesterone tablet 200 mg twice a day for 10 days.
Your doctor has rightly suggested you to stop the
Aspirin, in view of vaginal spotting.
I will suggest you to get a USG done to know about the viability of the pregnancy.
Please take rest.
Think positive.
All things will be fine in the due course of time.
I hope this answer helps you.
Thanks.
Dr. Purushottam Neurgaonkar.
