Don’t know how to feel

Hey everyone. This is my first time posting on this app. I need to vent and don’t know who to talk to since I have no friends. I have a one year old baby and currently my period is late around 2 weeks. I am going to take a test today. However I am disappointed because I don’t know how to feel I end up being pregnant again. I can’t say I would be 100% happy but I wouldn’t be sad. I guess I’m scared mostly. I feel guilty that I won’t be able to focus on my first born.
