Ovulation help

Hello ladies I need help with tracking my ovulation. I just ended my cycle and app says ovulation is in 3 days on the 30th, I’m confused because it is also telling me I’m in my fertile window but I took two ovulation testing strips today and both are negative. If it says I’m in my fertile window am I suppose to be baby dancing right now even tho test confirm not ovulating just yet. Or am I suppose to wait until the day I get a positive? So confused as to fertile window and ovulation day. pls any advice of help thank you ladies! Baby dust to all trying as well! ❤️
