Do you think I could be pregnant still?

I have gotten a postive PT at 3 weeks. I'm 4 weeks and 4 days, been lightly bleeding red brownish blood along with bloody eggwhite cm mixed it for 3 days now. And it looks like it's stopping. At first I thought I might have MC, but I am having no pain. And still having pregnancy symptoms such as, sore breasts and growth, and bloating and I threw up a day ago in the morning before I ate something and went to lunch with my friend. I am hoping and praying I'm still pregnant, but I need someone else's opinion or personal experience? Success stories or not .. please anything will help.
