BFP and Symptoms?

Rebecca
My husband and I have been trying for baby #2 since Jan. We had a miscarriage in April and FINALLY got our BFP today. Im praying for this baby to stick. This pregnancy is already so different. Is it too early to be nauseous? I seriously want to puke all day today, but I dont know if its because Im sick (my son shared his cold) or if its pregnancy related? Im only 3w4d
