33 weeks and pooping more than normal

I’m 33 weeks pregnant and a ftm. I normally have a bowel movement every other day,but the last 3 days I’ve been having 4-5 a day. It’s not loose or a lot either. I just get the urge and have to go. Is this something I need to let my OB know?

I’ve also been having more frequent Braxton Hicks and low back cramps
