Hello ladies. I am a newbie to this website. I am waiting for TTC. I am trying to get an idea of my ovulation signs and time. I started taking temperature 3 months back. I have a digital basal thermometer purchased from target. It starts to beep after about 30 seconds after staying in my mouth. But I read in one of my books on pregnancy that we have to let it stay for 3mins. The readings I get by both ways are different from each other. I personally like to leave it for 3 mins. Can you guys please tell me whats the right way. Thanks.
