Haven't had braxton hicks

I'm 32 weeks today and for a few weeks now my apps have been mentioning braxton hicks and how they will get stronger etc, but I'm certain I haven't felt a thing? I've even been drinking raspberry leaf tea which is meant to cause braxton hicks

I've certainly had pains feeling similar to poop cramps or period pains but have lasted for a few hours before disappearing rather than coming and going.

Should I be worried I'm not feeling anything?
