Bad thoughts about baby

Just posting this because I have to let my thoughts out some where. Sorry for the long post.

My first pregnancy I was a teen mother I was pregnant at 15 so there was so much I wasn't aware about, all I knew about was miscarriage, still birth and Down syndrome when I got pregnant I started reading books and learning that there is so much that can go wrong thank god everything went fine with that pregnancy I have a healthy daughter.

So fast forward six years now I'm expecting baby no. 2 (which was planned by the way) and this time around I'm aware of so much stuff, I got my bfp a day before my expected af, by now I knew about chemical pregnancies, so I didn't wanna get my hopes up till my first check up and till the doctor said everything was fine, then after my check up I couldn't help but to think all the time what if I miscarry? What if I have a missed miscarriage and I won't know? Just all these bad thoughts crossed my mind, I didn't accept the genetic testing because if anything is wrong I don't wanna stress thru out my pregnancy, I'm 36w2d and now if I don't feel her move I worry, I worry about stillbirth I worry that something is wrong with my baby and I feel like I'm putting all these negative thoughts,negative energy on to my unborn baby 😔 I just needed to let that out, I just want to have her and hold her and then I'll be at ease😞😞
