hi sis hoyhoy! congrats on your pregnancy. with your post, i assume voluntary member ka.
update of status - parang weeks lang, nabago na status ko from single to married. just present your marriage certificate sa sss office.
contribution - depends on you. ako kasi quarterly ang contribution. medyo hassle kasi ang monthly for me lalo pa at hindi ko maintindihan yung deadline nila.

ID's - hmm.. yan ang medyo may kahirapan. ako kasi, ang ID ko pa lang under my married name ay philhealth.
Philhealth - i think you need to go to their office para mag-update ng status. payment depends also on you kasi voluntary member ka.
also, inform kita ahead of time ha? ako kasi, nung nagpass ng mat2, hiningan pa ako ng 2 IDs under my married name na. pwera pa dyan yung sss ID. kaya medyo nahirapan ako ng konti. buti kahit papano tinanggap nila yung atm ko under my married name.
