Hi I had intercourse on 7th may after 4 days of my last period and took the ipill within 24 hours. I got withdrawal bleeding after 5 days of the pill. Bleeding continued for 3 days. Had another intercourse on 24th may with condom and there was no break off. Usually my periods were expected around 29th may, however I have not got it till now that is 6th june. All the pregnancy tests a re negative till today morning. Is it a side affect of the pill or what should I do now? I am very worried.
