First round Clomid/ PCOS/ Miscarriage

I just finished my first Clomid rx last night after our miscarriage last June. My cycles were all regular until then and now I barely have a period. I had to take Provera to induce this period and now it’s time to BD EOD until CD 20. I’m not very optimistic about this working but want this to happen more than anything. I’m also terrified of the fact that I might have another miscarriage. A lot of the polls I’ve seen look like the Clomid works more on round 1 or 4+. I really doubt it’ll happen for me and I’m just here to rant/whine guess. Has Clomid worked for anyone on here? I think I’m just looking for reassurance at this point 😕
