Blockage

So ladies I finally reached out to the lady who done my tubal reversal and told her I still haven’t conceived after 9 months. Well she asked me all the basic questions then said I may have tubal blockage. Like why wasn’t that explained to me before I paid all that money that even after surgery blockage could be an issue? I’m 42 I have no time to play guessing games. So now I have appt for blood work and then the 2nd of June I have hsg to see. Ladies what are your thoughts????
