Implantation Bleeding?

Alexus

Hi all! Some background for advice:

I’ve been on birth control since April to help “kick start” my ovulation. I’m hopes I can start TTC after stopping birth control in a few months.

I hadn’t taken it for a few days and had unprotected sex. It’s been about 8-9 days and I had some reddish brown bleeding. I long to have a family but I’m so scared to test and get negative and take my birth control.

My questions I have are: Is this implantation bleeding? When should I test to see if I’m pregnant?
