mom shared my pregnancy on facebook after being told not to... I'm 39 weeks tomorrow and we never announced to Facebook for a lot of reasons and she did last night and I'm crushed... my husband family didn't know if the pregnancy.. Not because we don't want them to but it's been high risk, wee lost our first baby and his mom stopped eating due to morning and depression.. they live 5000 miles away so it's not like they can be here to physically help Id things went wrong... so we were going to tell them when he was born and safe so his mothers health is sustained...its been hard not telling them but it's been for the best.. his grandmother has been sick and that added to the high risk pregnancy would not be good for his mom's health.. they are visiting in 3 weeks so they get to meet the baby thst will be here any day but my mom ruined the surprise... in praying they don't see it.. I've tried reporting it.. tried calling her and nothing... idk what to do... all of this because i won't let her in the laboring suit.. she did this when my last son died.. she blasted facebook how it was something i ate that killed him (false.. i had him due to ic, pprom, and chorio(.. just hate this..
