So I have been feeling a little tightness in my belly and pressure In my lower belly mostly and along with that pretty uncomfortable back pain and when that happens slight bit of nausea along with it , is this contractions?

Baby is still moving all around and they don’t seem really consistent or anything so far.. maybe have had 3-4 in the past hour but they aren’t unbearable or anything I would say mild ... haven’t had anything like this happen so far in my pregnancy and I’m also 35 weeks and 3 days

TIA ❤️
