Based on when I had my IUD removed, the latest AF could have POSSIBLY shown was the 23rd of May (yesterday) to not be considered late. My doctor told me to wait until next Thursday and then test and then call in however I'm switching insurance from my own to my OH's because his coverage is much better so I might just call one of the listed OB's and ask to get an appointment. Since I'll be a new patient, I'll probably have quite the wait anyway.
