Hi, I have gone through your question and understand your concerns. Not conceiving even after 2 years of unprotected intercourse, you are having primary infertility. Miprogen is progesterone which supports the pregnancy by making uterine environment more favourable for foetus. It may help you conceive, but your rest investigations for infertility should be normal. However, before taking any medication, I would suggest you and your partner to consult an infertility specialist to get properly examined, investigated and then further management accordingly. Hope you found the answer helpful. Wishing you good health.
