contractions? Braxton hicks? baby moving?

Renee
36 weeks today.  I started feeling discomfort in my pelvic area off and on... Inconsistent and not super painful.   I don't know if it's him moving and making me uncomfortable because I feel like these days he's in constant motion... Or Braxton hicks, I haven't had any of these yet or contractions starting...  I have an OB appointment tomorrow and I'm not super concerned.  Just wondering if I'm the only one confused about my body lol
