Hsg test / pregnancy

I’ve had a pregnancy back in 2016 but had a miscarriage at 12 weeks , fast forward to 2018 back in may I had a hsg done they said my tubes look good the dye went through good n my blood work care back good but i haven’t been able to conceive I’ve been trying since sept of 2017 , after my hsg the doctor said people usually get pregnant after because the dye pushes lil stuff that is blocking the tubes and people usually end up pregnant later down the road , is it my timing ? Should I try using ovulation kits ? Or what?
