Ay, hindi ako magsasabi na normal yan without proper check kasi it's really best to confirm with your OB directly, kahit kunti lang, better safe than sorry talaga, especially with pregnancy. A few of my mum friends had fluid around the umbilical area during pregnancy din, pero bawat case is different, kaya definitely worth a quick visit sa doctor para ma-assess properly and makapag-relax ka ng maayos. Wag mag-alala masyado, marami't maraming things can look scary pero usually okay lang, pero get it checked para sure ka na.
