Clomid help

Hi ladies!

I am starting my first round of Clomid as soon as I get my period. I have a couple questions that I can’t seem to find the answers to online. Please help if you have been on Clomid or have any experience on fertility drugs.

Should I be taking a prenatal vitamin while on Clomid?

What is the best brand of ovulation test strips available?

What time is best to test for ovulation? Morning or night?

How many days after my fifth Provera pill should I get my period?

If clomid does not work by the sixth round, can my OB/GYN prescribe Femara?
