Cramping from semen?

Kim
Hello!
This is my first month TTC.  I have never had the goods inside me until now and I had period-like cramps this week both times I had semen in me.   
I have a history with ovarian cysts and was feeling like I had one this month... Probably from stressing out about tracking my cycle! But that pain is different.  These cramps felt just like period cramps.  Does anybody else have this happen to them? Maybe I am allergic to semen?
