How many dpo am I?


Hey all

Im trying to figure out how many dpo I am. I had my period July 3-7. My app says I had a ovulation window from 19th-24. Which I believe is true because I had lots of egg white yellow tinged cm. My husband and I had sex the 19th and my peak day as my app says the 22nd. Yesterday I was so nausous I mean all day on and off. Food didnt taste good. Everytime I ate I thought i would get sick with a little cramping on and off. How many dpo am I?
