clomid symptoms

I am cd23 of my first round on provera/clomid (cd3-7). Just curious when your symptoms of clomid have been most common. I know they can mimic pregnancy symptoms. Are they in the days you actually take the pills or later on in your cycle? I had hot flashes right around when I took the clomid but I've had dizziness and nausea today with cramping that feels like af is on her way. (However, I have NEVER had this short of a cycle...my shortest cycle ever has been 34 days. Most recently they've been 50-75 days long. Thanks in advance! 💜
