Iui and constipation

I had my 6th round of iui yesterday. I was on 150 puregon and then did Ovidrel. Well today my first day after the procedure and I feel severe constipation and feel sore like when you have periods around my stomach but the worst is the constipation especially when standing. I've taken a Tylenol too...is this normal? I've never had symptoms like this the day after any iui and my 2nd iui was successful but ended in a miscarriage but I didn't feel this. Is this normal
