I had unprotected intercourse with my partner on saturday 15th april. He ejaculated outside my vagina but we were worried and took a ipill on sunday 16th april. After 5 days on 21st april I had withdrawal bleeding and it lasted for 3 days and ended on 24th april. Now my date of scheduled periods was 7th may and they haven't arrived. Does it mean that I am pregnant because it's been exactly 22 days I have taken ipill. Should I go for a pregnancy test.
