hi XXXXXX

Thanks for the query.

Contraceptive pills are prescribed in Poly cystic ovary disease for regularization of periods and to decrease symptoms of the disease,
Triquilar contains levonorgestrel and eithinyl estradiol in different combinations,
They can cause nausea and vomitings as side effects,
Generally after starting the pills in first few weeks women experience these symptoms because of hormones and they will subside soon,
So hopefully you also get relieved of them soon,
You can follow these general things like,
-avoid taking tablets with empty stomach,
-take tablets preferably at night,
After following this also if you still experience vomitings you can ask your doctor to change the brand of the pill, with her advice you can take anti-emetics for some days till problem solves.

Hope I have answered your query. I will be available to answer your follow up queries. If you are satisfied with all my answer, please rate the answer after closing the discussion.
Take care.
