ovulation

Emma 👨‍👩‍👧‍👦💖🇬🇧

Hi i have been doing ovulation test comes up with two lines one lighter than the other , the app says i’m not due for ovulating untill 6 days time. But i have what they call “ egg white “ all ready . so does that mean i am really fertile now? i have never had to track all this before as i fell pregnant very easily with my other two, but only doing this now because of my age i’m 38 . Any advice would help thank you
