first pregnancy

So this pregnancy thing is not only a first for me but a huge surprise. I'm 33 and have had multiple bowel surgeries due to Crohns Disease. Since I found out I was pregnant I've had horrible stomach cramping. Mostly up top on my belly where a crohns flare would occur not down where my ovaries are. I know you're not doctors nor do any of you know what crohns cramps feel like but I wanted to see if it was normal or if anyone else has experienced this to be in moderate to severe cramping pain for the majority of the day.  It's worsened after eating and I've noticed I'm having many issues pushing to poop. I'm hoping this pressure and pain is just my body changing and I'm just a huge woosie when it comes to pain.
