Implantation Bleeding vs Period

Tiffany
So I took a pg test last Thursday and positive since Sunday I've had light bleeding that's increased but still light. I've been told some women still have a periods in the first month even though they're pregnant. I took a test last night and it still said pregnant. But bleeding is there. I'm just worried. I have an OBGYN app on Tuesday. What do y'all think/suggest?
