I am six days late and have had regular periods in the past. I have had fertility treatments months ago but nothing as of recently. I have no symptoms except for frequent urination, weight gain, appetite increase, and fatigue. Should I call my doctor or does this sound like something other than pregnancy?

It's hard to diagnose pregnancy on symptoms alone but a visit to the doctor can tell you if you're pregnant or not.

Have you tried a pregnancy test using first morning urine?
