I am currently 7w 5days pregnant. I have been spotting on and off for a few days. It was brown at first. Lately its been pink. Sorry if it's tmi but I only see it when I wipe. I have also been having slight cramping in my right side, front and back. I have had a miscarriage before and I am wondering if I should be concerned. My ultrasound is in 4 days. I'm trying to hold out until then but the wait is killing me.
