Not sure of due date

Congratulations ladies 🤎🤎

Background: i stopped BC pill Nov 29 and tested positive the 27th of December. I’ll drop my calendar below but I never had a period and not sure when I ovulated.. we were just winging it lol 😅

But it would make sense that us doing it the 11th would be the week I got pregnant because the 24th is too soon to get a positive 3 days later ! My due date should be somewhere between the beginning and the middle of September !

Has this happened to anyone? When should I schedule an appointment and be able to see something??
