35 weeks

I’m 35 weeks pregnant and last night I started having super weird discharge. Almost like snot. Clear but a lot and it lasted until today. Every time I’d pee and wipe there was more. I think it was my mucus plug. I had minor cramps last night for the first time this entire pregnancy then they stopped this morning. Now about an hour ago the cramps came back. Idk if there Braxton Hicks or contractions or just cramps but they also hurt my lower back. Baby’s moving just fine and besides that I’m feeling fine. Should I be worried? Is labor near?
