Sayang, brown discharge or spotting lepas perjalanan jauh memang boleh happen, tapi we really can't say kalau itu sign bersalin ke atau tak, setiap pregnancy berbeza! A few of my mum friends ada lepas long drives, some beranak dalam seminggu, some lambat lagi. Kena call doctor atau go to clinic today ja, even just to check yang baby okay. Especially at 36 weeks, better safe than sorry kan. Don't wait to see what happens next, just go get checked out. Stay calm mummy, doctor will sort you out!
