So today I went to my doctor about birth control because I'm on a blood clot medicine for my heavy periods due to the side effects of bc. I plan to go into the Air Force and found out they allow birth control! I've tried a lot of different birth controls since 5th grade up until I was junior in high school and i noticed that I had side effects and it stopped working, so my doctor said the best thing would be the Mirena IUD. She suggested because pills have never worked and she said a lot of girls that went into military used that specific IUD. They put in in the uterus and enter it like you would a tampon, and from what I've heard it has minimal side effects. They said the worst side effect would be cramping for a little while. I've heard bad things about the IUD's that they insert into the arm so that's not an option.
