Im 34 weeks, cramping between mylegs in the tendons by my wohoo. Norm?

You and I are in the same boat.  I've been going through this since like 27 weeks when my tummy started shifting down.  my doctor said there are excrection ducts that help a woman function normally that run down our legs to our woohoo's.  These ducts can become swollen due to the baby and the position of your belly.  Apply ice when you feel swelling, massage the area to help ease the tension.  If you feel the cramping, just stop and stretch it as much as you can.  Wearing a maternity belt can also help get the baby up off the area.  I hate wearing mine, because it's not the most comfortable thing in the world, but I have to admit it helps a lot!  I also have a belly band that helps too (Old Navy, Target, Motherhood Maternity all sell them).  The way you are carrying the pregnancy definitely matters and I'm on #3 too, so stuff is definitely stretched out.  I cramp up so bad sometimes, I just have to lay out on the floor and relax until the cramp eases before I can go any further.  (I'm 32 weeks yesterday).  Try the maternity support belt - it will help a lot.  :)
