35 weeks pregnant and experiencing new sensations…?

At 35 weeks pregnant I have began experiencing Braxton Hicks contractions (I never felt them b4) and significantly increased baby movement in my lower abdomen for 2-3 days. Could this be a sign of impending labor or just the regular process as you get closer to 40 weeks? I havent passed any sign of my mucus plug and now the BH which were strong for a couple days are/haved decreas(ed)ing in frequency and intensity. My baby movement is normal. I'm totally confused about what was happening or is this normal? Thank you for any advice!!!
