At what point is being late, late enough? I have reg af arrive on the 8th of the month every time and lasts 4 days w/med-heavy flow. Last month my af came 2 days early (and 2 days after "relations" w/dh) not only 2 days early but only had spotting on the 6th and very light flow on the 7th and then nothing. This month so far no af. Not sure if I count from last month or usual date of af. So far bfn. Oh and we are ttc since August and 15d after ov. Sorry if this was tmi.
