Feeling sad and not sinking in that im pregnant.

So we had an early miscarriage in July and now we are pregnant again and we are so excited. I have gotten so many positive pregnancy test but still it dont sink in. This week is when my period supposed to come and im very anxious because last pregnancy was the miscarriage around my period. Im feeling sad, worried and all this feelings im not supposed to have but most important im scared to miscarry again. Advice? Anyone on the same boat at me? 😯😞😳😳
