My period was due the 12th (28 days from the first day of my last period) I started bleeding on the 10th but the next day there was no blood. Then on the 15th I had what seemed like a normal light period but it wasn't red as usual instead it was a brownish color. It lasted for 8 days and that just isn't normal for me. I had a miscarrage 2 months before this happened also. Could this be stress related or could it be something more serious cuase I'm completely clueless at this piont in time

Sounds like it may be implantation bleeding...
Is it possible that you could be pregnant?

I have been sexually active so it is possible. I didn't think I could get pregnant that close to miscarrying; especially since it took me a year and a half to get pregnant the first time.

You can get pregnant any time you have sex, period.

Also, you do not mention your age, this could be quite relative to your current situation.
