OPK + 7th AF due 21st

Hey looking for a cycle buddy. I have 32d to 34d length in my cycle. App says ovulation started around the 5th but I got my super positive surge on the 7th. AF is due on the 21st- the 25th depending on which app I am using (frustrating) The previous app I used never had my O day correct and I believe that caused most my problems. I am 33 with 3 girls ages 14. 10 and 7. Looking to give my DF his first child and we are getting married in 23 days. Need a buddy for my TWW!
