i have been spotting on and off for about 3 days now, only showing pink blood and pink cm on toilet paper when i wipe. no clotting at all. AF is due Jan 15th. i never ever, ever spot before AF and when AF arrives she is HEAVY, no spotting till about day 4/5. I have no idea what is going on and it's throwing me off because this has never happened in the 15 years i have had AF. Any of you ladies know what is going on or have any suggestions?
