Can a fertility monitor help prevent unwanted pregnancy??

I know some girls use them to find out when they ovulate so they can acquire pregnant, but can you use it to see when you are and afterwards avoid sex on those days? Will that work?

Probably since if you know you are ovulating and you chose not to hold sex afterwards you won't achieve pregnant. I don't imagine this should replace any methods you are already using to prevent pregnancy.

It should NOT be relied upon for this purpose. All it does is weigh FSH level and by the time the ovum have be released (when the FSH level are highest) it might be too tardy.

Sperm can live surrounded by the uterine cavity for up to 72 hours, whereas the fertility monitor usually give a 24-48 hour windowpane. That's not a risk I would be of a mind to whip!

No, solely penny-pinching prevents pregnancy for sure.

Nope, the rhythm method of contraception have the chief rate of let-down. You can obtain pregnant at any time of the month, but it is more plausible when you are ovulating.
