Hello sis, you can use your sickness benefit para hindi mo magamit mat leave mo. Ask your OB lang to provide you with a med cert stating na need mo mag bed rest for a certain amount of time. I believe pwede sya ng 3 months din. You just need to renew your request sa HR every 30 days. Then make sure you will still be able to continue monthly yung SSS, philhealth, pagibig mo para hindi maglapse. Ask ka din sa HR ng advise.
