almost 36 weeks

i am almost 36 weeks [will be 36 weeks this friday] and i am getting cramps like period cramps and sharp burst of pain in my cervix. this is my first pregnancy, so i am almost questioning everything. but is it to early to be feeling the cramping. i havent spoted or anything but the cramping and the contractions are getting worse day to day. and i get the cramps about 6 or so in two hours. could i be on my feet to much at work, and start cutting back on my hours cause, also i am retaining a little bit to much water even though thats all i drink. so is this normal to be feeling all of this this early well before my baby is actually full term. even though that will be next friday.

It's just the baby's head softening your cervix. Completely normal.
