Pinkish red spotting...feeling worried

Megan • Army wife and mom of 1 human baby and 3 fur babies!!
Hey all. I tested pos after heavy bleeding which I thought was my period...when it stopped I started feeling nauseous so I took another test. It was positive! I went to the dr yesterday for a blood test and it was also positive, going in tomorrow to get my levels checked again. 
Anyways, I'm having light pink/red discharge now. I had sex on Monday....anyone else having this??
