Clomid questions

Jessica

Hello, I've been prescribed 100mg clomid which i'll start in about 2 weeks (days 2-6). Looking at most posts on here, seems like people get prescribed 50mg first, why would I be given a higher dose? I have PCOS so could it be that? I'm not sure why but I feel nervous about it.. what days did you BD? Doctor said something about may advise (waiting on a letter with instructions) to use contraception until the scan incase of hyperstimulation and chance of multiples. Did anyone else do this? I feel that it would be a waste of a cycle if we did that! Thanks all xx
