I belive with 1st pregnancys, you drop a lot earlier.. I think i was about 32 weeks when i began to drop, and didnt have my son till 39.6 weeks..

I dont belive its an indication of labor being around the corner, if anything just means your baby is being a good boy/girl being in the right position (head down) and your body is just going with the flow..

Please dont stress about it...
