Third trimester

Anyone else in third trimester think it freaking sucks? I’m only about 30 weeks but I feel like I can’t do anything. I just want to get stuff done today.. cleaning, grocery shopping.. and every time I work for like 10 mins I start getting Braxton Hicks and feeling achy. Is my body telling me to slow down or should I power through it? Sigh.. i have had such an easy pregnancy until now so I feel like I’m probably just being a baby..
