Hi! I use the mabis bbt thermometer (cheap one you can find on amazon), but I think it is oral use only so if i wanted to/needed to temp vaginally, I would need to switch to the one I got from CVS that I don't like nearly as much.
I currently use both easy@home opk cheapies I got from Amazon and clear blue advance digital ovulation test. Moving forward, I will only be using the cheapies. Between temping and the cheap opks, I just don't need the other ones. It was, however, nice last month since my cycle is recently changed and I thought i was ovulating earlier than I am.
