Pregnant with Baby #2!

Hi Everyone! 
I'm a SAHM in Long Island, NY. I have a 18month old girl and just found out we are having baby #2! I'm 5w1d. I'm very nervous because last week I spotted for 7 days on and off. I haven't had any spotting for 2 days. My Midwife sent me for blood work today and this coming Saturday. I'm praying that my HGC levels show an increase. But I am so nervous that this pregnancy will not hold. Trying to stay positive.
