Hi all, I’m going to be trying tracking my BBT for the first time this month. I got the fermometer thermometer so was going to download the app but seeing as I already use Ovia and started with Premom last month when I started opks I was wondering if there’s any harm in just using my Premom app rather than having a third app? I’ll download and use Fermometer if it’s worth it but I’d rather stick to the two if it’s just as good! Thanks 😊
