Please read, needing info 😕

Today (11/12) makes 6 days of missing my period. I’ve always had regular cycles without fail. My first day of getting a positive on my ovulation kit was on 10/20 and my period was supposed to come on 11/7. I completely missed it but both tests I took (11/10 and 11/11 were both negative. I’m so confused and heartbroken bc it doesn’t make sense. The only other time I’ve missed a period was when I was pregnant with my child 10 years ago. I’m also 33 if that makes a difference 😔
