34 1/2 weeks pregnant and my sweet little girl hasn’t moved much in 3 days and I’m feeling lots of cramping on my pelvic…

Contact ur obgyn if you dnt feel baby moving much, also download an app keep track baby kicks 1-2 hrs 20 movements is a good thing

Hopefully it's nothing but the growth of your baby at this point she's going to start growing more rapidly. She may not be moving much because she's running out of room and you're feeling the cramps pressure and or pain do to her growing faster at this point.
