Thank You for your advice :)
The spotting may have been implantation bleeding. All you can do right now is wait for your period. If it's late then you can take a pregnancy test.
My period isn't due for another week or so and we had sex the 1st of this month
Yes, you could be pregnant. When is your period due? When did you have unprotected sex? If you were pregnant the time could tell me how far along you might be.
