For those who use the clearblue digital advanced ovulation tests

I started testing with these on cycle day 7. I had a negative test on CD 7, 8, 9, and 10. I had a flashy smiley on CD 11 in the morning (this morning) so I decided to start testing twice a day. Well I got a solid smiley face this afternoon, still CD 11. Does that seem weird to anyone else? That seems like a really really short estrogen rise before the LH surge. I always used first morning urine for the morning tests, so it wasn’t diluted or anything like that. It just seems like with such a short estrogen rise it wouldn’t have given my body time to prepare for ovulation?? I’m probably reading too much into it, we’ve been trying for about 2 years, I’ve used these tests intermittently and never had this happen before 🤷🏼‍♀️. Thoughts??
