Best OPK's??

[ameganh]

Okay, so I am ovulating this week, with peak fertility somewhere between Friday and Sunday. Should I get an OPK to determine when is the best time to try during that period? If so, I have 2 days to get a OPK. Is it too late? Anyone have any suggestions on which kind to get?

I used Clearblue Digital OPK's, they're so easy to use, a bit pricey but worth it as I got my BFP the first month of using them.
