Girls, can you please tell me if this could be pregnancy? I'm really worried because I had my last period on October 30th, and last month it wasn't. But around November 20th, I started feeling pain in my breasts, they first swelled up then became hard. The discharge is light like cream. I sleep a lot during the day sometimes too much, and I hardly sleep at night. Ovulation was around November 14-15th. I don't know what to do now, should I go see a gynecologist but first take a test? Or should I go see a gynecologist right away?
