I have noticed that the day my period ends, when I still have a bit of pinkish blood but the flow has stopped, I sometimes get some EWCM. It's not a lot but I can stretch it a good inch apart.
My fertility monitor tells me I ovulate about day 15/16 and I also have EWCM then, but a lot more.
So... is it just normal to have EWCM at the end of your period?
