Please help

I am 20 years old turning 21. By mistake my bf and I got pregnant but it was after we had been talking about children. After constant abdominal cramping it got worse and we went to the hospital. We found out that I miscarried. We were going through very stressful times , but once we had got on the right track I was still very upset that we had lost our child. So we decided to conceive. We are in a long distance relationship but before we left each other I was ovulating so we tried the entire week. I'm anxious to find out if it worked. It has not been after 12 days yet but I do feel bloated and tired. I am always urinating and today I found a discharge. It did not come with an odor. I don't know if I am thinking too much of it or is it possible that these are signs?
