i think with all the dif methods, opk's, maybe baby, temps, cm checking, you just have to find the one that you like the best and is easy for you to do. some people dont get very good results with opk's. i have seen a few people didnt liek the maybe babys. i know it doesnt really answer your question btu there isnt really one set method that suits everyone. i liek usign the opk's but it can become a bit expensive as i have to test mroe then once a day.
