First of all, because I'm sensing it's at the front of your mind right now - yes, most women with endo go on to have perfectly normal pregnancies. I have stage 4 endo and only one ovary and tube and got pregnant with no outside help whatsoever.
You'll find out more at your follow up appointment, but the fact that they've already told you that your remaining tube is working as it should is very encouraging.
As for recovery time - you kind of have to follow your own body with that one. It sounds as if your surgery was quite extensive so you are likely to be sore for a while - did they tell you how long to stay off work? With my last lap it was about 6 weeks until I felt 'normal' again but with other ladies it can take longer, or they can be raring to go again in a shorter time. The main thing is not to overdo it; stupid things like lifting a kettle can set you back, so don't try and run before you can walk.
Do you know how long roughly you'll have to wait for your follow up?
