Extra storage of fat is common in pregnancy most women I know got bigger in the back and arms, it goes away after baby
Dont feel like youre alone, im 3 days from due date and its like everything is goin to my back now!
Trust me...you will need a lot of strength in your back to carry around what's happening in the front. You wont just grow a belly...you will get round all around. Its OK....its all part of being pregnant
