Ovusoft symptoms and conditions

I had Mirena for 3.5 years and I also suffered from exhaustion, mood swings and bloating. When I got it removed with the hope of getting pregnant, nothing has happened for 6months now although my periods have become regular. My tummy still looks bloated and I fear that maybe the IUD damaged my uterus or something because I feel the pregnancy symptoms every month only to be disappointed with a period a few days later. Is anyone having the same trouble, not being able to conceive? I'd love to hear from you coz my OBGYN said once my period started, all should be normal.
