ESA Support Group (change in circumstances)

I had a medical for ESA last year and was placed in the support group for depression and anxiety. To my complete surprise I’ve found I’m pregnant (still very early). I’m in receipt of PIP with high rate for standard care and low for mobility.
I was wondering if I could get any advice about what to do and how my benefits would be affected. I would be bringing up the baby as a lone parent. When do I need to inform the ESA department. I’ve read you need to let them know 11 weeks before your due date? I’m also unsure whether I would be moved to income support or I would need to apply for universal credit. Any advice would be appreciated.

Thank you.

Well it’s hard to know how things will affect me. I do feel the added stress and responsibility maybe overwhelming. I’m looking at organising low cost counselling to have something in place. This was something I had intended to do even before. I’m just wondering at what point you need to inform the departments concerned. Do you think my benefits may change to income support or universal credit? Thank you Gordon for your previous reply.

Thank you Gordon.

Being pregnant would count as a change of circumstances in one way, even if the reason for the award still persists? Am I understanding that correctly.

Am I likely to face another medical whilst being pregnant?

Thank you
