I am not on birth control and have irregular periods. Last one was at the end of September 2011. My boyfriend and I had unprotected sex for a whole week. He came inside me on December 3rd in the middle of the night. We then had unprotected sex the next day(december 4) two different times where he came inside me both times. I went and got a Next Choice pill on December 5 and took the pill about 8:30pm.... I now have realized that I missed taking my 2nd dose of Next choice. Will the first pill be strong enough to stop the ovulation? Is it harder for me to get pregnant since my period was irregular lately? Any advice would be wonderful!
