Decrease in movements during contractions

Holly

I have been having contractions irregularly since Monday night. Now they are starting to get closer together, around 20 minute intervals and sometimes even shorter. I haven’t felt the baby move much since they have gotten stronger and more freguent. Only felt her foot in my side once in a couple hours. Is this worth calling my OB for? Or is this normal. Sorry I’m a FTM and just don’t want to annoy my doctor.
