contractions, BHicks or uterine stretching

okay this is my second child but i was induced with my first and wasn’t aware i was having contractions in hospital when they were monitoring me. i only recall the very strong contractions when labor started

now i’m pregnant 33 w some days (finishing up 34 weeks- this app) with my second child and it’s been a totally different pregnancy. the baby isn’t in the best position and he moves constantly..

anyway, i’m having a lot of tightness in my stomach every night for the past few days and haven’t been feeling myself. i was also checked for a uti (i’ve had to wait for results) because i’ve been leaking some yellow, some incontinence, but now i’m not entirely sure how to recognize contractions. last week i had crazy poops like 3/4 times a day and after that i felt unwell, and this tightness feeling it feels like a subdued version of labor contractions.. but i’m honestly at a loss as to what to look for..

this is a natural pregnancy and my daughter was ivf so any feedback on your experience would be awesome.. what to look for.. i know it differs from everyone
