Need encouragement

Diane
My baby sister just had her baby last night and I get to meet this perfect boy for the last 2 days I have been an emotional wreck my period was supposed to start on the 30 and still no sign of it coming but I'm not sure if I'm emotional bc of the fact that my son was in the NICU for 5 weeks but that shouldn't have started until after u saw him for the first time and it's been going on a week any suggestions or opinions
