Pregnancy after loss

I just recently found out I’m pregnant again after a recent miscarriage. I have a four year old son already an I’m wishing so hard for a sibling an another baby for this family to love but my fears of losing this baby like I did the last is overtaken my joy. I want to create a post for positive vibes and shoulders to cry on over such an emotional journey. Even though I’ve have a son this pregnancy so far feels like I’m learning everything all over again and can’t remember anything on how I should normally feel. I’m still super early only 5 weeks. Lost the other around 7 weeks and my dr appointment will be at my 7 week mark I’m so nervous. I’m excited yet still grieving, we truly didn’t expect to fall pregnant again so soon.
