Did clomid not work for your first child but helped you conceived your second child?

I took clomid for a yr never conceived with it. First month off of clomid I by some miracle conceived my daughter.

Well I'm back on clomid again to help my cycle and if I get pregnant that would be great. If clomid didn't work for me the first time could it still maybe work for a second child? 🤔🤞
