For about a week now (19weeks) I have felt like my tummy wants to explode! Its already quite big and im very slim but now it seems there is no more room for the baby and my skin is stretching! I guess the stretch marks will come soon. Anyone else finding this uncomfortable or is not bother to you? Im also feeling a little tired again which I thought I left behind in the first Trimester. I also struggle to stand. I can no longer use my tummy muscles I have to use my hands. I though this would happen when I was huge but it really aches to use my tummy to get up, sit up etc.
