I have a small hole in my heart so I’m not supposed to really take normal birth control because the risk of blood clots going to my heart and I also had postpartum heart failure so I was going to take plan b but isn’t it very concentrated birth control? Sorry never got into it because I was in birth control ( before we knew what’s wrong) so I’m not educated on the subject no ask your doctor comments I don’t have one currently because I switched my insurance and they won’t see me
