I had my last periods on 21st april. Then I had intercourse on 28th april. Ejaculation was done out of vagina. But still I took I pill within half an hour of intercourse. Then I started bleeding on 8th of may and continued till 20th may. Then I took almost 10 urine tests and a b- hcg test on 27th of may to make sure that I am not pregnant. All the tests are negative. I took my last urine test on 15th june and it was negative. I still have not got my periods. Are there any chances of being pregnant? When will I get my periods. Should I test again? If yes when? If no what should I do to get periods soon?
