Girls, I have a small panic attack. I'm 7 weeks pregnant and a couple of hours ago I noticed that my discharge is watery. But not bright red, but more like brownish (like the last day of menstruation). There's no pain in my stomach, just a headache. This happened during my second pregnancy, but only very slightly, and the doctor said it was probably capillaries ruptured. Has anyone experienced this? Should I worry? I'm going to the hospital only on Thursday.
