Inplantation bleeding?

Last night I whiped and had light pink blood, but not enough for a pad or tampon, well this morning it's the same but with a brown tint to it. And it's still only a little bit. My period isn't due until 2 weeks. Could this be Inplantation bleeding or a early period symptoms? If you think it's Inplantation bleeding when should I take a pregnancy test? Me and my husband want this so bad, this is the o oh sign I had of hope in 9 months
