Success with 100 mg Clomid odds

Sarah
I am in a cycle right now where I took 100 mg clomid. I had a miscarriage 4 months ago and am hoping we will get our bfp! We have a 4 year old and are hoping she will eventually get to be a big sis! We conceived easily with her and now this 2nd time seems to be a challenge! 
Has anyone had success on 100 mg of clomid?
