Constipation?!

An
I took 50mg clomid days 5-9 for my first time. i didn't think i had any side effects at all but i just realized it's cycle day 12 and i haven't gone to the bathroom since cycle day 7!! i'm really uncomfortable today. this never ever happens to me...usually i go 2-3 times a day every day. do you think it's from the clomid??
