My ovary is all gigantic

I went to my RE this afternoon after having some horrible cramping this morning.  After doing an ultrasound he told me that because I had so many follicles this cycle, my ovary is enlarged.  He said the follicles that were not mature at trigger have continued to grow.  Since there are a lot of them they just sort of ran out of room.  He said it is nothing to worry about, but I have to take it easy.  No bouncing around for me.    If I don't get pregnant it should calm down in the next week.  If I do happen to get pregnant, then it is something he will have to monitor, because it can get bigger.
