Pregnancy

Ma

Hey guys I need some help.

So I got positive pregnancy test about a week and a half ago. I went in to the doctors and they said it was negative. I’m currently almost 5 day’s late for my period to start. I have been having discharge and stuff and it kind of feels like I have a uti but not really. Today I felt really dizzy and sick to the stomach. I’m not sure what’s going on. Or can a chemical or miscarriage cause this? Anyone else experience this?
