LADIES WITH IRREGULAR PERIODS!

I want to know what you ladies did to be successful in getting pregnant, I already have a 1 1/2 old daughter , but my hubby and I are ready for another one. We've been trying since march of last year. I've tried everything, it's so hard because my period is so unpredictable , I've been tracking it, I've tried everything and not having any luck. I'm starting to get really upset about it. I'm not sure what else to do. I asked my Dr about Clomid , but she wants to wait and I can't wait any longer! 😥
