But AF really didnt show. I spotted thursday night- which I usually spot the day before AF..... then yesterday I had some red/brown CM- not alot so I wore a tampon to work. by noon it was barely anything on it. A little pink randomly thru the day and just pink tinge today- without CM. Umm?? could it be a late IB?? I tested but at my 3rd potty of the day. BFN.... not feeling any heavy cramping AF symptoms. And I am sure by posting this ... AF will show in full force. But really... any thoughts or opinions? I have 1 test left I can try tomorrow.
