Allowing myself to feel…

So I’m fairly new to this app, not really sure what I’m doing, but I just had to reach out. Had to see if anyone else can relate or understand this emotional hell I’m going through, trapped in my mind! This is my 3rd pregnancy, I miscarried with the first & got my beautiful 4.5 yr old daughter the second, & now I’m petrified of what’s to come this time. I’m very early in pregnancy (6 weeks), my husband & I started trying for another when my daughter was 3. Although we didn’t get serious about it, with ovulation tracking/tests, ect. until 2 months ago & boom we’re pregnant again! It’s amazing & I’m so happy & excited but I’m also unbelievably scared. Every time I get excited I feel stupid for being excited in fear somethings going to go wrong. I don’t remember feeling this much anxiety with my daughter, & she was conceived only 5 months after I miscarried. So I don’t understand why I’m feeling this way over something I want so badly! Sorry for the rant, I’m just riddled with worry. Anyone else relate or am I crazy?
