Hello everyone! The term is 18 weeks. Literally three days ago I started noticing greenish discharge on toilet paper after going to the bathroom. A little bit, once a day maybe. No smell, itching, burning, pain, etc. Sometimes it tingles in the area of the appendages. But as my doctor said, this is normal. The ligaments stretch. Before, the discharge was always yellowish. And they came out by themselves. And these only after abdominal tension, for example when walking long distances. Has anyone had something similar? To the doctor already 13. I'm thinking about going to get a PCR test done privately before that. I don't even know what to think anymore.
