6.5 weeks pregnant. Last night Started spotting brown, then pink, only when I wipe and not everytime I go to the bathroom. Very mild cramping that went away. Over night it turned redder but not as red as my period. I did pass a very small clot, but no pain. I feel very tired and lightheaded. Can t call my ob for another hour. Just want piece of mind. My fourth pregnancy (2 children, 1 mc)
