Trying not to stress...

So in March, I miscarried. It hurt me to my soul. I was traumatized because nobody told me (nurses and doctors at the hospital) what was about to happen (as far as passing the baby and sacrifice). So my husband and I decided not to try again until we have moved into our new house, I'm out of school (I went back to finish my degree), and we're more stable. I was suppose to start my period yesterday... Nothing came that morning. I felt nauseous throughout the day so I took a test. In less than 30 seconds...TWO lines appeared. My emotions are all over the place. I lost my angel baby and 2 months later I'm blessed with a possible. I'm scared I'm going to miscarry again. Any encouraging words...?
