I’m probably not pregnant right?

I had sex on July 9th with a condom and I’m on the pill but had missed my pill about a week prior. It says you have to wait a week. It was somewhere around there and a condom was used. The reason I’m stressed is because I’ve had like a brown discharge and read that it could be implantation bleeding but I think it could be from just the sex? Is it too early to take a pregnancy test? I’m a very anxious person so logically I’m telling myself I’m probably not but I need to hear it more I think😂 I’m also not supposed to get my period for another 16 days so I think it’s too early for implantation bleeding.
