8 w 2 d along after an ectopic

Parp
I had an ectopic pregnancy 16 months ago. I lost my baby and right Fallopian tube. Recovery has been a bitch, because of all my abdominal adhesions (scar tissue) post surgery. (Going poop is a 10/10 on the pain scale). 
Fast forward to November 18. I find out I'm pregnant. (We weren't trying, I've developed a sort of fear of pregnancy/babies after my loss). As each week goes on, I start to feel like this is real. But it is such a mind game. Am I really going to keep this pregnancy? Can I really create a little sibling for my little girl? I guess I'm having a super hard time trusting my body.
Today I woke up and I didn't have nausea and my boobs weren't hurting anymore. Am I going to miscarry? Am I just fine and now I'm overly sensitive to everything? 
Can you relate? I'm so excited if this is real. I've had 2 ultrasounds that show a baby in the uterus and a flickering heartbeat and normal growth patterns. People don't understand my hesitancy to feel excited. 
I'd like to hear your story and your feelings about conceiving after loss. Am I normal? Or have I just taken a trip down crazy road and I'm never coming back?
