Ttc for 14 months, with two losses. Positive test today!

I have received my first positive since my last loss in August. I immediately started obsessing, taking 3 more tests in a matter of hours. I was just hoping to see the line get darker or maybe I just couldn’t believe it. Now I find myself googling everything, every little twinge and the tiniest cramp. Is this normal, will it get better? I just want this baby to be okay! To see my husband crushed again and knowing that I can’t fix it really hurts. I have two other children that we love unconditionally, we just want our third baby to feel our family completed!
