Hi I'm no expert but do get a lot of symptoms/side effects taking clomid. I conceived first time on
5-9cd. If it persists get it checked
I have been on Clomid for almost 2 years on and off. I have had some cramping pain but nothing severe happen. It could be something to do with hyper stimulation of the ovary. Some people get that from Clomid. It can be extremely painful. You should talk to your doctor about this symptom, just to be on the safe side.
