First period after clomid

It's my first period after my first round of clomid and wow this is intense. I went through 6 super tampons yesterday and finally had to double up with pads as well. I woke up this morning to stained sheets. I leaked through a super tampon and a superb overnight pad. The cramps feel like my uterus is protesting being a part of my body and wants to run away. Is this normal???? I start taking round two of clomid tonight and honestly I'm a little scared it's going to make this worse. Motrin didn't help.
