How many days before o should I stop taking epo to make sure it isn't delayed from taking it?

thanks

I'll just stop a couple of days before and hope that's enough?

I'm not really sure, when I took it I took it AF-O and I eventually stopped taking it because my ovulation date was all over the place with it

Yes, we can't totally say because it will be different for everyone and even vary for individuals by the month, stopping CD 12 is a good idea but be taking OPK and stop at pos OPK if you get one sooner than that.
