32 weeks with back & belly pain

Hi everyone, I am a new time mom so please don’t judge.. I’m 32 weeks and I’ve been having these back pains on and off recently with some belly pain and cramping but it was only on one side of my belly.. I did a stress test 4 days ago and showed I was having contractions but I never really felt them, so I’m wondering what I’m feeling in contractions or just the baby herself, as I said this is my first baby I don’t know what to expect or what to look for everyone has different stories about how their Braxton Hicks or contractions feel like, I also have ALOT of pressure down there 24/7
