E.S.
Hi! I used OPK's, the 20 strip Answer brand kind, when TTC #2.
Had success on the 2nd cycle! We also used PreConcieve since I didn't have an abundance of CM at the time. And I kept my bum up for 30 minutes afterwards. We had been trying for a long time too (though I don't have PCOS) and I think these 3 things really helped us.
Oh and one thing I wanted to share was that the test strips say they are only good for 30 days...I used them after 30 days and concieved my son sooo...don't toss 'em if you haven't used them all up for one cycle. :)
Hope that helps!!! GL! Babydust!
