Need some advice ftm

Had my second antenatal appointment yesterday and to say I’m a little stressed out is an understatement, I have a uterus dydelphis (excuse the spelling) which is having 2 uterus and 2 cervix and because of this I have a high chance of pre term labour or loosing the baby. Doctor has said I’m not allowed on my feet for more then 4 hours at a time which makes being a causal worker hard. Has anyone got the same issue or anything similar and how did you cope. I was always told I’d never have a child so I’m beyond stressed at every little thing.
