Tummy Tightness

1st time mum here. I feel the same way. I experience tightness of my tummy since 3rd month of my pregnancy and it became regular basis when I enter my second trimester. It always happened during after lunch and there were times I find it hard to breath. I was worried before but whenever we had UTZ my baby is okay. So I get used to this kind of feeling. I still do some cardio exercises or walking so long my body does cooperate. Relax mommies, I was worried and paranoid with that experience and my OB says it's part of pregnancy when I told her "madalas naninigas tiyan ko lalo na sa upper part.
