Wa'alaikum assalam sis! Ahhh I understand the worry, catheter use postpartum is actually quite common, especially if ada complications atau tear yang agak serious during delivery. The best thing is to follow your doctor's advice on how long to keep it, and then when you go for your postnatal checkup (usually around 6 weeks), the doctor will assess whether you need it still or kalau boleh remove dah. Make sure during the checkup you mention any pain, discomfort, or signs of infection (like cloudy urine or fever) so they can guide you properly, your doctor is the best person to reassure you on the timeline sebab dia tahu exactly apa yang terjadi during your delivery. Jangan stress too much, okay, the body heals, and you'll get through this!
