In need of some positivity!!!!!

Thursday night I was just laying in bed and got to thinking, "damn, I havent gotten my period" had a couple tests so I took one! Wouldn't ya know! Positive! I want so badly to be excited and jumping with joy but I just had a miscarriage back in Sept and I am TERRIFIED that it will happen again, and I do not know if I can go through that again! I have a beautiful 5 year old, was a completely healthy and normal pregnancy, had the IUD after her for 3 years, got it taken out last Feb. Me and my SO started trying in June and by July I was pregnant! And then Sept I lost it 😐 We were not trying this time around, it just happened. I just would love some reassurance. Something, send me good juju for my precious rainbow baby 😢
