Theres a reason why we have two Ovaries...and that is, incase one go defunct, we got another! I wouldn't worry too much about that. As for the breathing tube, you really dont know it was (specifically) ever in. For me, it just felt like I had a little bit of a sore throat--like waking up after going to bed with a wet head
Its not so bad, plus your all hyped up on drugs, you you really cant feel anything
Bless you, and good luck.
