My cousin is having PCOS and irregular periods she has been trying to conceive for 2 years. From last january, she is having induced periods. Last month doctor gave her tab siphene 50 mg for 5 days from 2 nd day of periods along with metformin 500. She told that she had all symptoms of ovulation like sore breast and clear cervical mucus and she got her periods naturally. This month she didn't take tab siphene and she told that she don't think she ovulated. Her last periods was on june 27. This month she is going to take cap susten without waiting for 10 days and without taking a pregnancy test. Is it safe to take cap susten if she is pregnant?
