2nd Pregnancy

So, I was using glow to track my ovulation and prevent pregnancy! However, I took a pregnancy test yesterday and I'm Pregnant 2-3 weeks! My boyfriend is so excited! He has a 9yr old son and I have a soon to be 11yr old daughter! So, at least We will have little helpers! I'm having mixed emotions of confusion, excitement, exhaustion, nausea and shock! I have not been pregnant in 11yrs!!! I'm 32 and I feel too old and I had 2 miscarriages before my daughter and I'm nervous about that, as well! Do any of you expecting have older children?
