I've ovulated on day 14 the last 4 cycles Ive charted, with the exception of one cycle when I dont think I o'd at all, but FF thinks I might have on day 18. Anyway, Im on day 18 now, and just entered today's temp, and now FF has changed my O date to cd15. Why would it do that? Im very certain I o'd on day 14, because normally the day before I o i get cramps thats can last up to 2 hours.
I dont really think it will affect our chances of conceiving much this cycle, Im on a course of painkillers, anti biotics and anti inflammatories for another week, but Im just curious as to why FF would change its interpretation?
