Calendar or ovulation test?

So, this month I decided to follow my cervical muscus to see if the fertility dates in the calendar were right... it seems that I was supposed to ovulate on Saturday and we had some BD around the date but Sunday I felt like my CM was looking really fertile and yesterday I felt bloated, heavy raw egg white CM and so tired... I decided to take ovulation test when I got home after work and it came out positive! I told my boyfriend that and of course we had some BD last night 😍😉 Today my CM is still raw egg white but a little less than yesterday. Not doing any BD tonight but maybe tomorrow 😉

Do you use the Glow calendar or prefer to check your CM and ovulation test? I feel like this month my ovulation symptoms came after what was predicted...
