Went to the doctor due to brown spotting on the toilet paper only and cramping. I had a miscarriage before and was really worried. They did an ultrasound and discovered we have twins!!! It was too early to see a fetal pole but the yoke sacs looked good. The doctor thought the spotting could be due to implementation bleeding however 5 days later I still have light brown spotting on the toilet paper. Has anyone experienced spotting like this? I go back for another ultrasound in 3 days but my mind is so occupied by thoughts about the babies being ok!
