does clomid help if you periods are not regular. my periods use be regular but once i had my surgery to unblock my tubes i have not been regular. i was on premin for 6 wks and then megaproxyprogestrone for 10 days then birth control before and after my surgery for a month each time. my periods are not regular anymore. last time i had a period i was a week and half late, and was on my periond for 45 days.
