Do your fertile days differ on Clomid?

I'm on my second cycle of 50mg, my first cycle I got my high fertility result CD12 and my peak fertility 13-15 .. I'm now on CD11 and got a negative result but hoping my cycles stay the same and I'll get my positive results tomorrow. Although I've seen people say that ovulate late on Clomid or different days.... Just wondering if you ladies ovulation days differed each cycle and if so by how much?! Baby dust to all 💕
