*TMI PICTURE* Pregnant???

Hey ladies I was wondering if I could have your input on this. I was suppose to start my period Aug. 3 my periods are on time so I put a pad on expecting some blood, but when I went to the bathroom there was only a small amount of brown on my pad. Yesterday Aug. 4 (yesterday) the same thing happened with a very faint pink with it. Today I put a pad on thinking my period would start but more brown (attached is a picture). I didn't know what it was so I did some researching and found implantation bleeding. Has anyone else experienced this before and got a positive pregnancy test? Could I be pregnant? Was thinking of taking a pregnancy test when I stopped producing this brown stuff.

Side note I got married in June so we are happy newly weds (having sex all the time).
