I'm starting to get extremely nervous about my laparoscopic salpingectomy (tubal removal) on Wednesday... Tears right now. Please share experiences with me. I'm concerned about it's success (like as in death or complications), I'm emotional about not having anymore kids even though it's the best decision now, I'm afraid of post side effects...
