first pregnancy and super nervous.

Mary
So had positive pregnancy test on 9/3. Had blood work 9/7 hcg is at 204. This is my first ever pregnancy and im so scared. Im 32 5'4 and weigh 216lbs. My hubby keeps telling me to stop overthinking  it. Im so scared to mc or have something wrong with the baby. Ive had some friends go through some terrifing situations with pregnancy. Any one have the same feelings?
