let your own words betray you, just before i block you:

“are only fertile for about 4 days a month and shortly thereafter bleed for 3-5 days”   You have that wrong 😜.  It's the other way around

what does 'shortly thereafter' mean?

fertile 4 days, bleeding 3-5 days

i was wrong. 11-7 days fertile

i did not get the ordering wrong
