Is this normal?

I've been feeling a lot of pressure in my stomach/uterus area and having bouts of nausea single triggering on Saturday. Yesterday I couldn't run because it felt like my uterus was going to fall out of my V and when I sat down to fast it felt like there was a stick up there shoving my uterus up. That seems to have gone away but now I can't even put pressure on my stomach without pain. Is this normal after doing the Ovidrel trigger shot? Or something I need to call the doctor about? Does it sound like OHSS? I'm incredibly worried about it.
