maybe pregnant?

Melody
So 8-27-17 I found out I was pregnant,  very early like 5 weeks. But it has been 7 weeks since my last period. On 9-7-17 I miscarried. I have not had a period yet. But I’m super nauseous and my acne is clearing up along with egg white mucus. But I have had 2 negative pregnancy tests. Any ideas? Should I call the doctor or wait?
