am I being paranoid or is it early labor?

I'm 33 weeks pregnant and have had BH since about 20-22 weeks. Last week I started to have cramping that were stronger then normal and are 10 mins apart every evening (only in the evening tho) I also lost part of my mucus plug Sunday. My dr didn't seem too concerned said they are just stronger BH. But the last two days I have had  a serious burst of energy and very low appetite (compared to my zombie state and  eating non stop that I've been the last couple months lol) so I was just curious if maybe it's signs of early labor or am I being paranoid. And I'm asking here because I don't trust my drs judgment she is constantly getting me confused with her other patients and has gotten my due date wrong twice already 🙄
