Is it normal that i'm not yet to enjoy my pregnancy?

I am a FTM at week 12 pregnancy.. I am still plagued by morning sickness, fatigue, reduce appetite and mood swings. I am on tenterhooks everyday with this pregnancy because i had a miscarriage 2 years before. This pregnancy at week 10 i had a threatened miscarriage. But I am blessed that the baby stay strong with me till now. But because of all the above, i didnt not get excited or overjoyed that i am supposed to be on welcoming a new life. Is that normal?
