Clomid...major cramping and stomach pain during and after sex!

So this is my first month of clomid 50mg. I took it for 5 days starting the 14th of May. I have already ovulated and everything. Now im just waiting for my AF to arrive. Well the past few days ive experienced a VERY sharp pain in my stomach when hlwe have sex. I mean unbearable to the point where all i wanna do is curl up in the feedle postion. Last night the pain wasnt so bad until AFTER he finished. I couldnt walk...and i managed to head to the bathroom a few minutes after and by the time i sat down i felt so dizzy. I was trembling. I felt like i was gonna pass out literally. But i called hubby and he brought me milk and the pain and dizziness went away after a few minutes of drinking and sitting.Anybody know what this is or has experianced something similar? I think it might be clomid??
