How many days post ovulation am I?

Crystal

I get so frustrated with these OPK sticks because I thought I understood them lol I did take clomid days 3-7. I had 3 days of really dark OPK’s , cycle days 13-15. How many DPO am I and when do you think I ovulate? Early early yesterday I had egg white CM and the stomach pains for the remainder of the day. HELP!
