any advice would be helpful, thank you!

i’m a first time mom and 37 weeks now. just all yesterday i was really hungry and sooo thirsty. i felt like i couldn’t get enough water and i kept eating which is unlike me. then before bed last night at 1am i kept getting braxton hicks. i went to bed but would notice them here and there throughout the night as well. then all today i’ve had them but they don’t really hurt just uncomfortable mostly. all day i haven’t ate, i am so not hungry what’s so ever. i only ate a sandwich and food sounds so gross. i’m just wondering if this has happened to anyone else before going into labor? any comments would be appreciated. thank you!
