Uy, understandable na kinabahan ka, tatlong CS na tapos ectopic pa, you've been through so much already, kaya normal ang takot mo ngayong fourth pregnancy. Pero look, you made it through three times na, which means your body is strong at kaya mo 'yan, kaya please do talk to your OB about your concerns, they can monitor you closely this time and ease your mind with regular check-ups. You're doing amazing by taking care of yourself at your baby kahit anxious ka, and that kind of mama worry actually shows how much you care, you've got this, mommy!
