3rd baby and terrified

Hi everyone

I’ve known I was pregnant for a few weeks now still not sure how far along I am yet because o have hat the ultrasound yet. I am so scared about this pregnancy and having a 3rd child because the two kids I do have are a hand full my kids will be 6 and 2 by the time baby comes but I literally have no family support where I live and the family I do have around me are not in one way but supportive and I’m also scared to even tell her (her being my mom) that I’m pregnant Bkuz I’m already feeling sad about this pregnancy and I feel like her negative reaction is going to make it worst. I know no one can really tell me what to do but I just needed to vent and maybe get some positive feedback with mothers of 3 kids and how they even manage things!
