Fam vs. Advanced

LadyFlyAway · #1 July 9th, 2009, 04:43 PM

With the Advanced setting, my O date is listed as Monday July 6th. But, while playing around I switched to the FAM setting and it changed my O date to Sunday July 5th...why? Which one is correct? Which one should I use?

I am not sure why they switched it to Sunday with the FAM. I think Monday is correct. But, they use different criteria for determining your o date. This isn't an exact science. I would choose the day that you feel most lined up with your fertile signs. Use your CM as a guide. If you still had fertile CM on Monday I would say it was more likely Monday but if you were pretty dry on Monday it could have been Sunday.

I really don't know what date to use. My CM was very unfertile to me during the time of either O date. My OPK's were dark on Sunday, but the test line was darker than the control line on Monday so...I'm not sure. I guess I will just have to say I am 4 or 5 dpo and so on and so forth.

I changed mine to FAM method because on another tracker I use it changed it by 3 days so I wanted to see what FF did. I did not get any EW CM, but probably don't have enough temps in prior to O'ing for the FAM method. My OPK was still positive in the evening on the 17th. This is all grrrr to me right now! lol I guess after a few cycles it will be easier to understand, but I don't want this to take a few more cycles!!!

The open circle on your chart makes it harder to read. I have charts like yours a lot where I am not totally certain which day is the right day. But, you can definitely tell you ovulated which is really great. Not too much longer before you can start thinking about testing!
