Taking Plan B twice in one mensural cycle? Help!!!

I’m having a bad month. I took plan b on the 19th of this month (a day after ovulation) because of the condom breaking. Today is the 30th and again, the condom broke and we didn’t realize until after we were done. (Definitely getting new condoms) According to my calendar that is mostly accurate, I’m supposed to get my period tomorrow. I do have all the normal period symptoms that I usually get. I do have Plan B handy to take again, but do you think it’s necessary? I’m also worried about taking it twice in one menstrual cycle. I feel like it may throw my period off and I’ll just be worried about being pregnant every day I don’t have my period. Do you know if there are health risks or a higher chance of getting pregnant if I do take it more than once in one menstrual cycle? Please help me.
