TTC for 2nd for more than a year

Hi All,

I am 31 years old. We have been trying to have our 2nd child from october 2019 and no luck yet.

I got my tests done with obgyn and my husband had his tests too. Everything came back normal. I already used 5 cycles of clomid and didn’t help.

We had our 1st child in 2016 and no issues.

Has anyone had similar situation with unexplained infertility? Should I go see any specialist?
