Maybe baby?

I have two apps that I use to track my cycles. This one and ovia fertility. I trust ovia because I've used that one most and it's been accurate but I just started this one for more help. Ovia says AF is due tomorrow but this says in 6 days. I haven't had any premenstrual symptoms except bloating. Not much cramping but like I slight tug feeling under my naval. CM is creamy and I think the position is Med,soft, and closed. What should I expect? When should I test?
