Can you tell the difference?

Can you tell the difference between the two thermometers shown in the picture? Well, one is a regular thermometer and the other is a basal body temperature thermometer. On the surface the only difference (besides the pretty pink tip) is that the basal body temp one carries the temp out to 2 decimal points (fancy, huh?). Well, I decided to start charting my temps again. Last time I talked to my friend Jennifer (who also has PCOS and 3 wonderful kids) she mentioned that it is helpful to chart your temp and watch for ovulation. Back when I first went off the pill and didn't have a period, I charted for about 2 months. When I didn't see any changes (and still didn't have a period) I stopped. This was back in February and March. This time charting my temperature I was able to start on Day 1 thanks to the Provera. The whole point of charting your basal body temp is to see when you ovulate. Simply, your basal body temp (resting body temp/lowest body temp achieved) will raise after ovulation. If you chart your temperature cycle you can begin to predict when you will ovulate. You are supposed to take your temperature at the same time everyday. It 's supposed to also be right when you first wake up and after at least 3 hours of continuous sleep (although 5 hours is recommended). This again causes a problem for me like the peeing on a stick. I wake up everyday around 330 or sometimes later to pee. I have been taking my temp at 6am which so we will see what happens. I don't know how long I will stick out the temperature taking. Makes me feel like I should be sick. Some people even use this method as birth control prevention. That's dedication. Well anyways... that's the difference.
