... realized that the condom had broken. We are almost sure that the condom broke after he took it out but as a precaution I took Levonorgestrel 1.5mg the next morning. I had my regular periods on the 30th of May. I was expecting my next periods on the 28th of June but it is the 29th today and I am worried. I have always had regular periods and no health problems. Is it possible that the pill had an effect of my June cycle when the period immediately after taking it were normal?
