Abdominal and rectal pressure?

Question

I am 13 Days Past a IUI , and I never cramp before AF ( she would be due tomorrow)

Last night when we had s*x and I orgasmed, my uterus cramped up and then it relaxed.. it was uncomfortable but was not really painful.. today I went to the bathroom # 2 and shortly after my whole lower abdomin got crampy and really painfull, I also feel rectal pressure..

That initial crampy feeling has now gone away and I can better describe it as constant pressure.. Please let me know what you think..also only serios answers

Thanks

If rectal pain is combined with abdomen pain, then it's possible you are having a back labor.  Rectal pain is also a sign to push but I think you'd know if you had been having contractions for awhile.  

Either way, since you are so close to your due date, you should go get checked out just incase you're one of those women who don't have very painful contractions.  Also, sperm can naturally induce labor so there's a chance you started something when you had s*x.

Edit:  Sorry I didn't know what IUI was...
