Bh & lower back pain

I have about 4-5 BH an hour and now i started having lower back pain, kinda like I do when I get my period. Also a little lower stomach cramps here and there. I’ve been drinking water and relaxing so idk what is going on and if it’s something I should be concerned about if it lasts? I’m 34 weeks. i also eat, drink, and do all the recommendations—maybe this is just the reality until she’s here lol. Also FTM and nervous I’ll not realize when I’m in labor since I know people who don’t get the horrible contractions until it’s too late
