Who can help me at this time???

Hi everyone who’s still awake! I started a thread a while back about mothers-in-law.. And mine is disgusting. Always shouting that I can’t cook or clean, that I look like a hussy because I don’t wear a headscarf, asking for money every week, shouting that I’m still a baby myself so why should I have a child, I’d better give it to her.. etc etc.. Well, a few weeks ago she said yes, I’ll temporarily come live with you guys so I can help and give advice.. (while she doesn’t even speak the same language as me and I have my own mother whom I do ask for advice if needed). Luckily my husband put his foot down then and said we really don’t want that and just want to be with the two of us in the last few weeks/days.. Well, today I’m exactly 41 weeks pregnant, and I’m being induced tomorrow and we wanted to keep that secret from everyone so it would still be a bit of a surprise.. Well, the mother-in-law knows that they’re inducing you when you’re 41 weeks pregnant, well we got a call 2 hours ago from my husband’s sister yes we just put mom on the train she’ll be at yours in 2 hours (the train from Paris, we live in Brussels) she just didn’t tell anyone she was coming, and now my last evening cozy with the two of us with my husband is completely ruined and the plan to keep it secret too.. I got so angry I’m still trembling and can’t stop crying, I’m now arguing with my husband even though he really can’t do anything about it (because he didn’t know either) last evening nice with the two of us is completely ruined and that while I have to go into labor tomorrow and I also just fell not on my belly but on my bottom and back.. I don’t know if the baby is okay, what do you think? Should I go to the hospital now to have it checked or should I better just try to calm down and wait until tomorrow? I’m incredibly worried and it’s not really making me calmer.. I hope you guys understand the story a bit..
Love, Manon
