I should be 6 weeks! Help!

I have not had my period in 3 weeks. We were trying but kinda lost hope for the time being. My last period was 4/8. I took a test and it was a very faint positive. I’ve taken plenty others that say negative but I’m to the point where my boobs hurt, I can’t eat without feeling nauseous abs I wanna sleep all the time. My doctor said I couldn’t come in for another month. What should I do?
