Went to the doctor today to confirm my pregnancy. I went I'm the afternoon. Drank a lot to make sure I could pee. I am just over 4 weeks. Got three positive tests at home, one right before I went to doctor. Their test came back negative. They looked in my vagina, saw yellow and light brown discharge. Said it could be early period or early miscarriage. But then also told me that urine test could come back negative due to time of day or drinking too much liquid before. I am not spotting or cramping. Just went to get labs done waiting for results. So confused what could this mean?? Is there any hope😔😔
