TTC/fertility issues?

Latasha
I'm having pre period symptoms. Cramping, over emotional. But I was due for my period yesterday. So I'm one day late. I took at at home test that said not pregnant.  My boobs are swollen and that's one symptom I've never had before a period. Should I just wait a few days and then see a doc? 
Also, after how many unlucky months should nt husband go to check his fertility? His ejaculation is usually very small amounts every time we do anything. I don't know if that's normal.
