About a couple nights ago I woke up at 9:30pm to a lot of brown discharge and when I went to clean up and use the bathroom a bunch more dropped out into the toilet it was thick and a brownish color. I just found out I was having twins and it's probably me just being paranoid but I'm scared it was me losing one of my twins. I had no cramping at all my doc office is closed last Friday of the month so I couldn't call him but I called the hospital OB nurses and she said it sounded strange but it also sounded like old blood which means I shouldn't worry. Has anyone had this before and if so what happened
