HELP 😫

I started testing ovulation yesterday on a Clearblue advanced digital and it said low fertility, when I tested again this morning I got the blinking face meaning medium fertility. I’m just wondering if anyone else had that and was still successful getting pregnant? I’m just concerned it hasn’t tested enough low fertility days to know when the LH surge is rising if that makes sense?! I started testing on cycle day 9 like the chart told me to.
