i use both, fm is best for knowing when your fertile days are coming up, but temps are best for telling when you actually do ov.
last month my fm said peak days were earlier than my actual ov day. FM peak was day 15 or 16, so thought i was gonna ov on day 17, but actually ov'd on day 18, so not much different, but i might have stoppped bd if i was just relying on fm. Not that it made any difference this month still not pg!
