We are ttc#2, and my strategy has always been JS - no charting etc. But my cycles are all over the place following a mc nearly three months ago (currently day 39, no sign of AF, bfn...) so I want to use opks just to have an idea of if/when I'm ovulating - will still be dtd every other day but would like an idea of wtf is going on if possible. Don't want to spend a fortune though - has anyone found any cheap, reliable ones?
