Try and be brief, changing a few details so as not to out myself.
Visited family, ds there too who is in early stages of pregnancy. Had been chatting about scan, dates etc.
At time of leaving I say goodbyes, have good week etc, to ds are you 12 weeks tomorrow then? She replies yes. DM says 'leave her alone, her baby not yours.' I feebly laughed it off and left. But still thinking wtf.
Was I BU?
Ds and dm v close If that makes any difference?
