I missed four pills and didn't realize it but when I did I took two pills and later that day I got my period early and was told to stop pills and let period run it's course and but a new pack. my problem is We had sex the four days I missed and twice after My period was over. None of these times we used condoms. Are my chances of being pregnat really high now? This is first time I have messed up my pills this bad since I started taking Ocella two years ago.
