Can a miscarriage block your tubes

Iv been ttc for 2 years I'v had 2 losses first was at 8 weeks September last year and then second in December at 5-6 weeks when I had my first the full sack came out of me and u was checked by ultrasound to see if it had all passed but with my second I only bled for short while I asked to be checked over but was told it wasn't necessary. Since then I have not been able to concieve wich is now 10 months ago im convinced there must be some kind of blockage since my last loss. Iv had all infertility test done and they have came back all good I did have an hsg though and the dye didn't go through my tubes wich indicates blockage but the doctor said she thinks it was due to muscle spasm. Iv asked for a laporascopy but I'm kind of getting messed around in really depressed with it all I just want my rainbow baby.

Any advise
