Ovidrel Weight Gain/Swollen Body

Since taking the Ovidrel injection 3 days ago, it feels like I put on 20 lbs. I am really puffy and just don't seem to fit in my clothes...even ones I wore last week fine. Is this normal? If so, how long til this stops? What can I safely do to lose this excess weight? Also, prior to the Ovidrel I was on clomid and hormones to bring on a cycle. Is all this related?
