If you are talking about menstrual type of bleeding, it can be normal. If it is time for your period, things may be a little off. Keep in mind that your body just went through a traumatic ordeal, so it may take your body a few cycles before it gets back to normal. Incisional bleeding needs to be looked at quickly. Call your dr and ask them what their opinion is. THey will let you know if they think you need to be seen.

Are you referring to menstrual type bleeding or incision bleeding? Incision bleeding needs immediate attention from your doctor. The other can be stranger than what you normally get. It should subside with time.
