Ovulation test issue - 1st time TTC

I am 40 and divorced and he is 40. First time TTC for both of us. We both want to be parents and have not been doing anything to prevent a pregnancy and decided to start TTC.

I don't know what to think. I went and got an ovulation test. Took my first test Thursday and Friday were ○ like I thought it would. Saturday was 😊 high and the test stuck. It kept the 😊 all day Saturday and Sunday. Monday morning it looked like it was back to normal. So I took the test and it showed ○ and today ○

According to my chart I should be fertile April 28th - May 4th with the 2nd or 3rd as my "peak" so do I assume that test is broken or do assume I am not going to ovulate this month.

I think I have been showing signs from what I have read. I have been horny, my breasts hurt and a my CM is matching the chart for being fertile.

What do you think?
