I was on previfem for 1 month. I went off it on my placebo week and stayed off it for another 4 days and had sex on the 11th day being off the pill (including 7 placebos, missed 4 actives basically). He did cum in me. Then I started a new pill a few days later, different brand. He cummed in me on the 4th day of being on them because he misunderstood me and thought they were effective. Is there a good chance I could get pregnant?
