An endometrial ablation is NOT birth control..it is very dangerous if you have one and get pregnant. Any good doctor will not do the ablation until you are sure you dont want children, are done having children and you significant other is using protection. Novasure is one of the brands used for an endometrial ablation and is supposed to have a better success rate. My dr did my ablation using Novasure in the hospital (outpatient procedure) so he would be able to monitor my symptoms. My POTS specialist faxed him a letter staing I needed 3 bags of lactated ringers, 1 bag before, during and after the procedure. I was under anesthesia for the procedure and would highly encourage that. From what I have heard, it is very painful. After the first month, the flow was very light and is even lighter now. When an ablation is done, it does not affect your hormones. So if your symptoms are hormone related, an ablation wont help but if your symptoms are from large blood loss, this may help. Good luck! Liz
