Does anyone know?

I had a m/c 5 weeks ago and came up with 3 positive pregnancy test this week.

When I called vitaline they told me either it's from the m/c or I'm pregnant. The doctors had told me my levels went back to 0. After the m/c. I haven't throw up like I did with my other pregnancies but I've felt sick and sensitive to some smells. I'm sore all over and always tired. I am calling the obgyn today but could just really be pregnant again this soon?
