Girls, I need advice. In about a day I'll be 23 weeks. Today I was lying down, turned over and noticed my pajamas were wet at the breast—on one breast—transparent, sticky, no smell. Has anyone had this? I understand it could be colostrum, but I read that it should be yellow and that it's abnormal for it to leak from only one breast. I have a scheduled appointment with my gynecologist soon, I'll definitely ask her everything, but maybe someone has experienced this—I've read so much now I'm scared.
