I started a new job 6 months ago and found out I was pregnant a month later. Shortly after this my partner left me. It's been a really stressful time but I've tried to keep my head down at work and still deliver. It's a stressful job and I'm underesourced (several open headcounts in my team for a while) and I've flagged bandwidth issues many times and kept my manager in the loop on my priorities by weekly emails and meetings.
I told work I was pregnant 2 months ago so we could plan ahead for maternity cover.
I had a 6 month probation period which I just had a review about and they said they're extending my probation for a month since I haven't delivered a specific project which my manager wanted to see done. I have been working on it but it's not complete due to bandwidth issues which I'd flagged previously. He hadn't mentioned any issues with my performance until a month ago when he said he was disappointed this project wasn't completed. Since then I started focusing on this project and have made a lot of progress which I shared with him before my review but he was a bit dismissive and only wanted to focus on why it wasn't delivered before and implied I wasn't hard working enough. I was told that the 3 outcomes of the review in a month is that my probation is signed off or extended or my contract terminated. I asked for clear deliverables that need to be achieved by this date on email.
However I feel so stressed about this hanging over me. It's been a really really hard time emotionally due to the break up, pregnancy hormones and workload levels. I'm now struggling to eat and sleep (often sleeping less than 4 hours) and in turn feeling anxious about the baby. I will only have statutory maternity as is and no partner support so I can't afford to just leave but I feel really worried about the physical impact of this stress while pregnant. HR knows that I found this all very upsetting and stressful so not sure what else I can do but just get on with it, however I suspect now they just want me to leave so the situation feels hopeless. I feel very isolated, unsupported and depressed and not sure where to turn.
