Pregnancy Test Help

UPDATE:

Hello Ladies.

I have the Nexplanon implant and possibly am having signs of early pregnancy. I want to take a pregnancy test but I don’t have my periods anymore so I don’t technically know if “I’m late”. Is there a good amount of time I should wait before taking the test? Thank you! ❤️

Update: I stared bleeding two days after having sex but the blood wasn’t red, it was a pinkish brown color. I just wanted to be sure. I’m on day 3 of bleeding.
