Advise needed

So I miscarried in the 29th of July this year I’ve had a period 4 days ago I felt nauseous for a week before and the 5 days of and 3 now going on 4 days on and off after my period yesterday I found out my mum is pregnant (yes that right my mum and I’m not happy about it) and today I’ve started feeling that baby feel you get in your belly that feeling went away 24hrs after loosing my baby and all tests were negative after 24hrs is it possible to get this feeling due to recent events as much as I would like to be pregnant again I know it’s not that
