I guess you could have it and not know but not to have any symptoms at all would be strange but not impossible. I have had both since the age of 14 (28 now). I feel sick for half the day most days but full days during ovulating. My cycle has never been normal (frustrating!!!) and when it is that time of the month the pain is so bad sometimes it's hard to breathe. I get shooting pain constantly through my back & stomach and I can only liken it to being stabbed (I've never been stabbed so I can't say for sure). I have just had my most recent lap 4 weeks ago and whilst they did not discover any new endo, I was given the lovely news of only having one working tube (but surrounded by scar tissues because of all the other laps!!!). I must admit I have not done all I can to understand my condition(s) but after not being able to concieve for 5 years and starting to feel quite sad about it, I thought it was about time (hence the reason I joined this board!!!). If money is not an object I would say to you to have the lap done as soon as you can, then you don't have to wonder do I or don't have it.
