Ay sis, nakaka-alala talaga ang brown discharge lalo na first pregnancy mo pa! A few of us moms experienced something similar and honestly, it's so common with subchorionic hemorrhages, one of my close friends had spotting from week 6 all the way to almost week 14, pero normal naman ang pregnancy niya in the end. Since your OB already confirmed na healed na siya at she's not worried, that's a really good sign, kaya I think you can breathe a bit easier na. The spotting usually tapers off within a few weeks or months once the bleeding spot closes up, pero every pregnancy is different kaya better to just follow your doc's advice and come back for that follow-up ultrasound after a month para makita niyo talaga ang progress. Try not to stress too much because stress doesn't help either, you're doing everything right na with bed rest at following orders!
