(((Imminence)))) - I'm so sorry you're faced with this decision. I don't want to judge you but I hope you don't mind me saying a few things. Ultimately this is YOUR decision in the end. Would you be willing to get a 2nd opinion? They could also put you in the hospital if your pregnancy or you become in danger. As far as the money goes, there must be a way to get around that. In addition, since you had such a traumatic birthing experience this may be frightening to think something else could go wrong.
I don't want to confuse you more, but please make sure there's no other alternative before you make this choice. Often there are deep emotional consequences after this procedure. I think all doctors and pharmacists should put a huge warning and consult with a patient about antibiotics interactions with birth control pills. Hugs
