I understand what you are going through. I had a tubuligation while I was delivering my second. My daughter was 11 pounds and the doctors were having a difficult time getting her out of my ribcage.
With the tubuligation during my 2nd C section, I ended up getting an infection both of my tube. The infection was so bad that I almosted died on the spot. As a result, I ended up having to have a partial hysterectomy. I had no history of endrometriosis so the doctors concluded that the organism was introduced into my tubes when they seared my tubes during the C section.
Is there a way that your husband would go in for a vasectomy? You will experience a great deal of complications, between the hormonal changes, psychological problems, lessened sexual desire, possible medical complications during and after surgery.
I would just advise you to make sure that you have exhausted all other possibilities before you go through with this partial hysterectomy.
