Hello everyone. Don't read if you're squeamish. In general, on Monday it will be exactly 36 weeks since I had my last checkup. Today evening after cleaning, something became slightly damp, took a pad and wiped myself to see what it was, there were light yellow-green discharge, not yellow or green for sure, mixed, not slimy like regular discharge but another color, also earlier I had constipation, now everything is fine, several times a day, maybe it's somehow related? Has anyone experienced this? What could it be?
