Baby #2 and still nervous during the first trimester!

Ladies- this is baby #2. We are only 5 weeks and 5 days- 13 weeks feels so far away!!! I’ve nervous even though my last pregnancy was PERFECT from beginning to end. I have a sweet little almost 11month old! I think I’m more nervous bc this was literally the first time having sex with no protection since my daughter was born so it feels so unreal! But 2 pregnancy test last we are positive. We had a miscarriage in 2016 so I was nervous with my daughter and now this sweet bean! Any tips on how to put miscarriage in the back of my mind? I feel we will be ok! But still makes me a tad nervous!
