FTM, preterm labor concern? TMI...

Everyone keeps talking about signs of preterm labor... This may be a really dumb question, but I thought it might be worth asking. I am 34+1 weeks with my first. I have been having a lot of discharge lately, I had horrible pelvic/lower bump pains this morning, and I have been popping a lot more than before. It was every few days for the entire pregnancy, sometimes not very much since they were more solid. Now I have been going at least twice per day and although they aren't lose, they are frequent. I haven't been able to go like this since before pregnancy. Could this mean anything? I have not had contractions or BH today that I know of. My back always hurts, and normal discomforts. The pelvic pain first thing in the morning caught my attention though.
