Early ovulation

I miscarried in December, I am 41 my cycles are about 32 to 33 days with just one day heavy a day light and the final day very light spotting. My ovulation tests were usually positive around cd17 and 18. After miscarriage in January ovulation tests states at 17/18 positive. So planned on trying again this month and I decided to start my ovulation tests on cd l12 to have baseline and the test was positive so I did my digital clear blue and yep peak. So of course I had my best friend give me his sample ( I am already a single mom and my best friend is helping me to have another). So has anyone experienced ovulation coming earlier than usual? Should I be concerned with the egg like is it mature enough? Well now it is the waiting game to see if the egg and Soren will meet
