Ladies is it normal to have a period when you spot the first, heavy flow second day (heavier than usual) with really bad cramps(cramps only lasted the one day), medium flow on third day and  fourth and nothing on the fifth. My period is normally 7 days and is medium to heavy.. it was a week early this month as normally have it on the 1st of every month.. today when I wiped after using toilet I had pink fertile cm? Never had that before and it was only the one wipe..nothing else... anyone else had this? Ttc and not on any new medication or not doing anything different...
