I have pcos already have kids unable to conceive suffered ischemia stroke from metformin and hormonal birth control should i try clomid (clomiphene) or femara?

Maybe either: In the us these drugs are only available by prescription, so i'd direct you to ask your own doctor. If they are available without prescription, it's your call. There are risks and side effects you should be aware of, but again its usually with a doctor to guide you. I'm afraid that discussion is not doable in a short online answer.
