FTM here and feel like I’m losing the plot 😂

for the last two/ three days I’ve been getting pretty uncomfortable ‘contractions’ or what I assume to be contractions, but mainly it feels like my stomach is all tight and uncomfortable and then it’s slightly less tight and uncomfortable 😂 this will go on all evening until I manage to get comfortable enough to fall asleep. At which point they stop and I’m pretty much okay all day.

Last night they would start in my back but definitely don’t feel like ‘waves’ and for the life of me I couldn’t have timed them because the inconsistency was just frustrating! Also not even 100% sure it’s not just baby moving awkwardly and I’ve got a bad back from being busy all day 😂 but there was moments it was painful enough to take my breath away!

Suppose my question is just that is this anything to worry about or am I worrying for nothing? Im only 35+3 so not expecting to go into labour soon!
