Clomid question!

Hey there ladies, so the first round of clomid was a bust

I will be starting round 2, but first I will need to take provera to bring on my pd. Before all of this I’ve always been punctual on my periods and well I have a 4 year old little girl who was conceived naturally. Doctor doesn’t understand why I haven’t been able to conceive because I’m thinner than when I got pg with my first. (I know God has his plan 😊). Question is, did any of you ladies have luck in the second round taking 100mg?
