Low lying placenta at 18 weeks

For working mamsh dyan, sinong nakaexperience dito ng low lying placenta at 18 weeks (early 2nd trim), without bleeding, inunfit ba kayo or pinagbedrest ng OB nyo? I'm totally fine na, no more SCH but my ultrasound today says i have posterior low lying placenta, for fit to work ako dapat pero bukas nya pa mababasa ang result ng ultrasound ko. I'm just hoping na ma fit to work ako kase need na mag ipon since 3 months nakong unfit due to sub. hematoma and palapit na ng palapit sa katotohanan. Hirap maghanap ng gagastusin pag walang sweldo.
