Implantation bleeding?

ch

Hey guys so I tested positive 2 days ago at 10 dpo. Today test is darker but I’m cramping a lot and noticed super super light tinged discharge. It’s like the lightest pink/orange color. I’m just scared.. since I already tested positive doesn’t that mean I already implanted? Or can you implant after you get a positive? Please help! I had 2 miscarriages 10 years ago with my ex. I’m now married and this is my first pregnancy so I’m really nervous. Thanks for your help.
