losing confidence

For a few days now I've had brown discharge. I've heard it's just old blood coming out slowly and it's normal. I've also heard it's a sign of an impending miscarriage. My boobs are still soar, and I'm still a little bloated. I should add that they believe I have a bicornuate uterus, and I'm only 7 weeks today. Has anyone had experiences like this? I need reassurance and honesty!!!
