Being pregnant but not knowing if I’m having a baby 💔

I’m trying to be hopeful but I just feel… broken. I have a sch that’s getting bigger and I feel like I have no one. Dad won’t even help with our toddler because he doesn’t know how to be around me rn and I’m terrified that anything I’m doing with my baby is increasing the chances of losing this one. I’m struggling and I hurt ALL the time. I feel so alone and I get that he’s struggling with this too but it’s making me feel so much worse. It’s making the situation worse I’m not meant to lift our toddler rn, I should be on bed rest but that isn’t really an option rn. I’m completely failing my baby girl and when I do try I’m putting my other baby at risk 💔 I’ve had to go stay with my mum because it’s Halloween and I’m not even going to be able to do anything with my daughter, I’ve asked my auntie to take her out for a bit so she isn’t totally missing out but this isn’t fair on her. I mean it isn’t fair on any of us but she doesn’t even know what going on she’s just constantly wanting up for cuddles and I feel like I’m turning her down when I don’t lift her. I get down to her level and give her cuddles when she does and she usually turns round and sits on my knee. I don’t know how to cope with any of this and I don’t know what to do 😭😭😭😭
