Sayang, bleeding at 27 weeks kena check serious-serious, walaupun DH dah pergi hospital & dapat ubat + injection, kalau still on-off like that, you really need to go back or call your doctor immediately, okay? Jangan tahan-tahan. Better safe than sorry lah, especially this far along. A few of my mum friends went through scares like this & the doctors were really helpful once they knew what's going on, bisa ada explanations yang totally manageable, tapi kena confirm dengan medical team you. Take care of yourself, & don't hesitate to go balik A&E if it gets heavier!
