Hi, I took two i pill within a week after having sex with my boyfriend, both of them withing 72 hours of having sex. I had my date of scheduled period on 3rd of April. I had sex last week of march and took the second i pill on 28th march. I did not bleed after it at all. I had little symptoms of nausea and abdominal pain which are common after taking contraceptive. Now, I am really worried since its 9th of April and I have not got my period till now. I would also like to mention that i have irregular period sometimes and i have been travelling during this time and so it has been stressful.
