sup ladies👋need some of your thoughts. please try and keep positive😛so im 24 and unfortunately had to move back home with my mom 16 months ago(was living in fl alone). i met my man and started dating him soon after that and i love him very much! he lives with his family as well. my mom is very over protective and of course like any mother wants the best for me. she has expressed to me on some occasions she isnt the biggest fan of my bf saying he doesnt make enough money(shes so materialistic!) and how his family sounds like trash. he needs to go back to school.yada yada. also she continually says how i need to be on b.c so i dont get pregnant and how i shouldn't get too involved with anyone....like why?! im at the point in my life where im thinking about marriage and kids. shes had bad experience with men and started having kids at 18.in result shes been single for ten yrs! so she thinks i should be single too or something. ive had a stillbirth in 2012 and i think shes scared if i got preg it would happen again..but i just found out yesterday i am pregnant!🙏😍i feel so blessed. but i am so scared to tell my mom because i feel like she'll freak out and i wont get support. atleast not at first. shes constantly saying dont get pregnant.well here i am. what do i do? how do i tell her and when? i personally want to wait a while but its so hard hiding it from your own mom who u live with.its just us in the house. what would u ladies do?

*edit: no i dont plan on living at home when baby arrives and i also pay to live here.
