Help please ?

Hi momshies! i'm 27 and i'm on my 5th month of pregnancy. Pero natatakot ako sabihin sa family ko at di ko alam kung pano ko uumpisahan sabihin dahil alam ko na magagalit sila. Mejo halata na baby bump ko pero sila di nila nahahalata at ewan ko kung bakit. Asking for any suggestions on how to say it to your parents?
