Brownish Discharge at 27 weeks

I informed my doctor right away and inadvise an ako complete bed rest lang. I was not advise naman na mag ER and nafefeel ko rin baby ko na gumgalaw. Ano kaya ang possible cause bakit ganito and tingin nyo need padin pumunta ng ER? . Anyone na naka experience din neto? #pregnancy #firstbaby #advicepls
