Ttc after miscarriage in April 2018

Lately I’ve been super tired and it wasn’t me that noticed it was. Hubby he said I’ve been falling asleep very fast today I was. At work and got up fast and got dizzy having super thick white creamy discharge according to glow i ovulated about 5-6 days ago and I’m sure I did as I had the egg white discharge then we went to dinner tonight and I was kinda crampy lightly in my back and lower abdomen I took a ovulation test just to see and it came out positive of course I BD BUT I’m just wondering is it possible to be ovulating or ? Why do you think is going on needing some help! AF IS DUE JANUARY 8th
