Hi girls! Just started my period yesterday and decided to start temping this cycle. The pharmacist at my drugstore said there's no difference between digital normal and basal thermometers, but I read online that there is so I returned it and didn't start today. I'm going to start temping tomorrow. Is there a difference between the two? And any tips/lessons learned? It seems fairly straightforward, but I thought that about the OPKs and learned as I went. Here's what I think I've learned to try differently with the OPKs: When I get a second line, test throughout the day until it gets darker...I missed my darker line, I think. Just tested at 12pm, 6pm (70% darkness both times) and 12pm next day it was faded to 50%, 12pm next day gone. And I've heard to test around 2 pm--heard it's better, don't know why. And to hold urine for 4 hours (if I can!) even though the test says to lessen fluids 2 hours before (so hold it from 10, reduce liquids at 12, test at 2 I think!?) Does this all sound right? It's my second cycle with OPKs and 1st with BBT, so...we'll see! Fertility Friend didn't detect my ovulation without BBT--I want to do it and be sure I'm ovulating!!!
