alright ladies i need to hear opinions. as you can see in the chart above we havent baby danced much this month so i figured I wouldnt worry and try next month. however yesturday i had barely visable pink discharge and some brown discharge today. i do not nomrally bleed after ovulation and just had a pap smear and blood work done a month ago which is all clear. what could be the cause?
