Hi there! (forever lurker, first time poster)
I'm in my first month of charting and the cheapo BBT I bought off Amazon without reading the reviews is not working out--it takes 4 minutes to register a temperature and has no memory function. I could live with the lack of memory function, but the 4 minutes is killer in the morning (and also--so uncomfortable!)
I'm hoping for this to be a long term birth control method, so I'm okay with making the investment if the best choice is more expensive-I'm just not having much luck sorting through options on Amazon.
What are you using? Any suggestions?
Thank you so much!
