No prob Skyla. I know, it is very daunting when you first start on this site. There is heaps of good advice to sift through. The girl diet is pretty hard which is why people who have been swaying girl for a long time tend to drop a lot of it.
There have been some studies done which show that a woman can O more than once a month, and a lot of women get pg nowhere near their menstrual cycle O. I've read that Jonas discovered it while trying to help Catholic women avoid unwanted pregnancies. The women would BD during their period as they thought that was completely safe, but they were still getting pg. The lunar theory does not say that you will definitely O every month, but more that if you do have a lunar O, it will be at that date and time. BDing in the days leading up to the lunar O is supposed to cause the egg to be released, which would be why they say you must do it at least 24 hrs before O is due. There is quite a bit of info in the Odan websites FAQ. Your Odan calendar will tell you exactly what time to BD, and there are examples of the calendar on the website too, so you know what it will look like.
The lunar zodiac calendar matches your gender calendar. You can compare it with the dates from astro.com. It is extra helpful if you are TTC with your menstrual cycle O. For example, you got a +OPK today, so you would expect to O within the next 24-36 hrs. Because we are in boy time until late on the 4th, it seems likely that this month you would O in boy time. Once you keep track of your cycle for a few months, you might start to see a pattern before, during or after you O. I seem to O 30 hours after I get a +OPK, so I can decide if it is a good month to TTC a girl. I am going to TTC with my lunar calendar first but if I am not having any success, I will likely include both O times (if they are girl of course).
O+12 is very tricky to get right. It took me 3 months to know what my body was up to. Then even when I knew I had got it just right, it didn't work anyway! If you do your temps each morning it will help you confirm when you have O. I track mine on fertility friend. Also keep a close eye on your CM so you start to see a pattern of when you are highly fertile. A lot of women use their lunar dates and fertile CM checks to avoid getting pg. When used in combination, they are supposed to have a 98% success rate. Anyway, as you can tell I find all this fascinating. I have certainly learnt how to avoid getting pg, now I just need to switch it around and get pg (in 2012)!
