It is unlikely that you are
pregnant.
You had unprotected intercourse during relatively "Safe period". After that you had emergency contraception too.
You are overdue by 2 days only. Please wait for another 3 days. After that you can do Urine
pregnancy test.
If it is negative , you should wait for another 10 days (because you had withdrawal bleeding on 3 April). After that you repeat urine pregnancy test.
