Whenever it feels like coming back normally. It takes awhile for your body to get back into the swing of things. If you're breastfeeding it can take even longer. Even though my first period came back a few months after, it still took several months for it to be normal. All I can say, is be prepared with some tampons/pads, but don't expect it to be normal for awhile. If it doesn't come back for awhile, don't be freaked out either. I felt better with a few dollar store pregnancy tests in the house. Even though we were using stuff to prevent any accidents. But sometimes when your system is still getting back into whack, it's better to know for sure!
