Blocked tubes

Have any of you ladies been tested for blocked tubes?  We are ttc number 2 and it's been over a year.  I'm really worrying and stressing about why I'm not getting pregant.  I'm so worried something is wrong.  I had a cancer scare back in June, having an irregular pap.  During all that testing and craziness a doctor I had just met casually mentioned after we deal with this we may need to check if my tubes are blocked.  I have to have another pap this month to make sure I'm ok, and I guess I need this test done to check my Fallopian tubes!  Ugh I just don't understand.  I got pregant the first time while on birth control!!  I thought I would have such a easy time getting prego again and I'm not at all!!!  I have very regular periods and always have the watery discharge around ovulation time.  But month after month here comes Aunt Flo and I'm feeling heartbroken.  Right now I'm in the 2ww period.  Fingers crossed this is our time, but if not I would like to hear some experiences with having tubal blockage!  Thanks and sorry this is soo long!!  ?
