Pregnant again

hello everyone. i am a little scared. i had a miscarriage back in november. i was just shy of 3 months pregnant. it was my very first pregnancy and i was so excited until that day i started bleeding. now here i am. i missed my second period post miscarriage so i thought to take a test and when it came back negative i would relax and my period would come. but yesterday when i peed on that test and it came back positive, i felt the fear sink in. i am so scared i will go through another loss and i won't get to see anoyher baby that i had made inside of my body. im trying to be positive but it is so hard. the memories of my miscarriage are still fresh. i dont know what to do. im just going through the motions.
