Mama, this is definitely something na kailangan mo i-check with your OB agad, especially since may cervical changes na at discharge changes, hindi ko magugess kung anong meaning nito for you specifically, kaya please don't wait para dito. Brown discharge near the end of pregnancy can mean different things, at kailangan ng doctor mo mag-assess ng situation mo personally. Go to your clinic or hospital now if pwede, or call your OB right away para malaman mo kung okay lang or if you need to come in, better safe, di ba? You're so close na, mama!
