Aw, congrats sa baby, mommy! Try asking sa QC health centers or barangay health stations kasi mura talaga ang prenatal checkups doon, and some offer free ultrasound din, maraming single moms na kami sa circle na nag-avail dito and okay ang service. For tipid tips, I'd say mag-invest sa prenatal vitamins from the start, eat lots ng eggs and affordable proteins, and join Facebook groups ng single moms kasi andami sharing ng discounted maternity clothes at baby stuff na sobrang helpful! Pero para sure na healthy ka at baby mo, importante talaga magpacheckup regularly sa doctor, wag mag-skip kasi matataggal lang siya sobrang importante, and mas mura pa ang prevention than emergency. You got this, ate!
