Im scared

So in January i had a miscarriage and it shattered me i could function like normal for two weeks. I felt like it was all my fault even though i know it wasnt. Well a few days ago i noticed my period was late which isnt normal so i took a test and as it turns out im expecting again. I have my first appointment set up for the 30th and at first i was really happy and excited but that quickly turned to fear. Im trying my best to stay positive and not stress but i dont know if my husband or i could handle that kind of loss again. Anyone have any advice to help get me through until my appointment?
