Marriage status update

Hello mga mamsh. Hmm Just graduated (kasal) October 2018 then nitong Feb just got preggy. I wasn't able to update my surname yet kasi nagwwait pa kami ng psa copy. Then now, im planning to update my status and surname sa goverment like philhealth pagibig and sss. However, nagddalawang isip ako if pag magupdate ako ng status ko sa sss, magkaproblema naman po ako sa pagkuha ng mat benefits. My due date will be on Oct. What to do mamshies?
