Wah sabar ye, kena cervical abrasion memang scary! A few of my mum friends went through something similar, the bleeding with sneezing or straining is so stressful, tapi biasanya okay lang if the wound is minor like doc said. Since you're already seeing your doctor and they're monitoring (dengan sample results coming), just follow their rest advice closely, try to manage that resdung best you can (maybe saline spray helps reduce sneezing?), and go back immediately if the bleeding becomes heavy or you get other symptoms. GBS itself doesn't always show obvious symptoms like heavy discharge, so trust your doctor's diagnosis and they'll guide you through it. For now, rest, hydrate, and try not to strain, I know easier said than done with that sneezing! Keep your follow-up appointments, you're doing the right thing.
