Could be in trouble...weight gain!

lckytabby3

I have already gained 16 lbs.  My rings are getting tight.  Not sure why though because I have weighed more then this before and my rings were never tight.  I go to OB Friday and I am pretty sure they will say something.  I am only supposed to gain 20. I have gained 6 in the last month.  I am just hungry all the time and M/S comes when I dont eat.  I guess I should start walking or something.  Is it bad to go from no activity(Been scared to move since BFP) to being active? 

Any suggestions?  I know I can't go back but how to I keep from gaining so much.
