36 1/2 weeks and already feeling contractions?

©assandra • 32 yr old wife and mom of 2 wild boys and 2 angel babies. Due in March 2016 with a little girl!
This is my third baby and I usually have prodromal labor for about 2 weeks before I give birth. (Regular Braxton hicks and 'labor' starts and stops)...
This time around, those symptoms have already started! Have any of you mamas experienced this? I want her to wait to come until I'm at least 37 weeks! She's already dropped (per my midwife) and I am having crampy regular Braxton hicks just laying here in bed!
