I was due for my second shot on the 11th of this month but I didn't go in for it because I have gained some weight and did not want to gain more.. and the past few weeks I've had some unexplained bloating, stomach hardness. and I look to be about four months pregnant.. and I pee a lot because of the pressure on my stomach.. I'm not sure if this could be a side effect of this medication but just let me know please..
