Immediately after delivery, you will have a bloody discharge (lochia) from the vagina. This will turn pinkish within a week and become white or yellowish after about 10 days. Lochia may last for 4 to 6 weeks, but it should be less bloody after 2 weeks. It can come and go for about 2 months.
Use pads, rather than tampons, during this time. If you have a tear next to the vagina (perineal tear) or an episiotomy that is healing, change the pad at least every 4 hours to prevent irritation and infection.
Call your health professional if you:
Don't be concerned if you pass occasional blood clots, as long as they are smaller than a golf ball.
