sorry if this is tmi, but if you had sex recently, sometimes light bleeding can happen a day or two after, but as long as it's light and there's no pain with it, you should be okay. I would still talk to your doc or maybe call a nurses line to be sure, but I had that happen when I was pregnant with my daughter & I was freaking out since I miscarried the pregnancy prior to her, but the doc calmed me down and everything was fine :)
hi due to the minimal amount of bleeding it may just be inplantation bleeding where the egg attaches itself to you, as long as it wasn't a lot of b!leeding mixed with period like cramps i would say you are perfectly normal! congratulations on your pregnancy!
