Clomid?

Jessica
So I see many women on here talking about taking clomid. I get that it helps with conception but does it also help regulate periods ? I havent had a period since beginning my bc two years ago, removed my bc 2 months ago and still nothing. It's making it hard to track ovulation because my hubs and I are ttc. Also is it doctor prescribed or otc? And how much does it cost? What's your experiences on it? Ect?
