Braxton hicks

I'm almost 32 wks w baby #3 & never felt them w other pregnancies. This time I've had them since 2nd trimester. Usually when I'm teaching group fitness & in my 2nd hour. I think Bc my body just needs a break & dehydrated (I do drink 25oz water per hour @ gym) The last 2 weeks I've been having way more. And relaxing & drinking water doesn't make them go away like usual. Started having period like cramps as well last couple days. I have condition that sometimes causes preterm labor, but I only have a mild case of it & should b fine. Anyone have Braxton hicks so early on & still make to full term. I'm supposed to be induced by 37 wks, & even that early worries me... I see the perinatologist every week & last wk my cervix was still closed 👍🏼
