Implantation Bleeding or Early Period?

I'm about a year into TTC for baby #2 and I was on the verge of giving up. But this month AF was due July 11th but on the 7th I started this brownish/slightly red discharge. It didn't flow like my period normally does(super heavy then moderate, then super light) but it still lasted about 4-5 days. None of these days did I feel up a pad. I didn't go through this with my 1st child but I know every pregnancy can be different. I'm going to take a pregnancy test the 13th 1st thing in the morning. But I was curious as to if anyone else has experienced this and the outcome?
