I started charting our first month ttc thinking it might take awhile
My advice with that is to get a good thermometer..I have a BD brand basal that I got off amazon that works great..just steer clear of the walgreens brand it's horrible! It does have to be a basal thermometer..they're more precise than a regular digi. The only hard part is you pretty much have to temp at the same time each morning after getting at least 3 hrs of sleep..I just set an alarm and go back to bed to make sure it's accurate. As for the opk's I buy Wondfu's bulk from amazon..I get 40 opk's and 10 preg tests for 13.95..that way you can take two a day and not break the bank!
They really sound more complicated than they are..with the opk's you have to test in the afternoon and your test line has to be as dark or darker than the control line..you'll definately know your positive when you see it! Sorry long reply!
