Clomid side effects?

Chelsey • 2 years of Trying for our 1st Baby, now working with fertility DR. In the midst of the storm,God will be your Sunshine!
This is my second round of clomid 50mg and the side effects seem stronger this round!
Effects: stomach pain and cramping, headaches, nausea, dizziness and severe HOT FLASHES. 
The effects started about 30 minutes after taking the pill. 
Anyone else going through this and having same experience?
