plan b twice this month

unfortunately i had to take plan b twice this month. let me say that this is not a birth control alternative and i understand that. both times the condom broke and it was a mistake on both of our parts. the time frame between those are two weeks. i took them right away after the incident and im planning to get on BC so this won’t happen again. how will this affect my cycle? has anyone went through the same thing? and please don’t tell me that i can only take it twice a year. i can’t find any articles that support that. ill listen if you’re a nurse or a doctor.

*please don’t tell me im irresponsible or stupid as well, we all make mistakes and im doing my best for this to never happen again.
