*TMI* Labor soon?

I’m 33 weeks as of today and I’m normally constipated while pregnant going maybe once every couple days and yesterday and today I have been pooping a lot (4 times today and a lot) and tonight I had these intense back pains that almost felt like I was having Braxton Hicks in my back or something. They only lasted for a total of maybe a minute or two but off and on. This will be my first vaginal birth so I don’t really know what to expect. She still looks like she’s sitting high and hasn’t dropped low so maybe it’s nothing. What do you guys think?
