Clomid

Hi, has anyone used clomid? Just wanting to find out the best days to take it when i get AF?

I do ovulate on my own however havent been able to get preg?, my doc seems to think this is the best option for me as i just need a boost. I am not being monitored i have 3 months supply and to go back if no positive by month 3.

I have 50mg clomid.

I usually get AF for 7 days, should i do it from 3-7? I dont know whaf other days to take it have just been advised to take for 5 days but skip the first day?

Any suggestions? Thanks
