CD 55 rn. No period still. Super light spotting CD 23-25. Breast have been super sore past week and I’ve been super super fatigued lately. Lots of white CM Been having shadows of a line but no apparent positive yet. Just confused. I had a early MC in October. I was only a few weeks along. Last af 11/18-11/23. Could I be pregnant???
