Doesn't feel real

Latasha

So I have taken 7 hpt and all have came out positive and I am still in shock I believe, because it doesn't feel real. My calendar that's going by last menstrual says I'm 8 weeks n 6days prego. I am so afraid that I'm getting my hopes up to only find out other wise. Is this normal? My last pregnancy I lost my sweet baby at 18 weeks so this baby is our rainbow baby. We have been trying for 3 years. I am just so afraid.
