Encouragement

Hi Ladies,
I have been ttc for about a year and a half. In November I found out i have PCOS and needed help to conceive. I've gone through 3 rounds of medicated cycles with timed intercourse. This past cycle, I had blood drawn 3 times, had 3 ultrasounds which showed I had 2 follicles and everything looked great. I administered an ovadrel shot and hoped for the best, really thinking that this time would finally work...
Yesterday however, I got my period and now have to do it all over again!! 
I'm really getting frustrated and loosing hope and I am looking for some encouragement or hope to keep me going! Please!!
