Pre term labor?

Marian • 22 and expecting a little princess💕🎀
Hi ladies so I am 35 weeks, and I've been having the worse Braxton hicks for 2 days now but today it's a little worse but the thing is they are still berable to me. Like they don't have my on the floor wanting to die but they do have me in bed curled up waiting for them to subside, I also have lower back pin and it feels like I have to poop but then I try and I can't. Could these be signs of early labor or I'm just crazy ? Help! I'm a first time mommy so I'm not sure what I should be expecting, I also feel her moving more then usually today a lot.
