Does being dry down there mean I wasn’t ovulating? Or could it mean I’m infertile ?

Iknow the app just predicts when it’ll start but I’m just curious because I did have sex in those windows also but like I said I was very dry so no type watery egg white like I normally get close to the fertile/ovulation phases. So my ovulation was predicted to be today but for the pass few days I’ve been very dry , no discharge at all. I had stretchy cm earlier last week but none recently
