Stressed! 😖

So I have an almost 3 year old, (she’ll be 3 on Saturday!) a one year old and I just found out I’m pregnant with my third! I’m not stressed about another baby, but I’m stressed because my fiancé and I have been struggling financially basically living paycheck to paycheck so kinda stressed about that. Also I’m scared to tell my mom. 😂 she wants Mmmm at happy when I got pregnant the first 2 times and really wanted me to wait to get pregnant again, but we’ve been trying for almost a year and a half and nothing so I really wasn’t expecting to get pregnant 😂 buuuuuut how do I tell my mom?? 🤦‍♀️🤦‍♀️
