Baby Name???

I'm 9 weeks pregnant and I don't know what to refer to my baby as. I don't feel right referring to the baby as "it" or simply "the baby". I see my baby as a person and want to give him/her a cute little nickname:) What did you call your baby in utero? My cousin called her son "Angel" and my friend called her baby "Sweet Pea". Ex.) We were crib shopping and my friend said "That's perfect! Now we just have to get the bedding for it to match Sweet Pea's room!"
