anyone have answers for me?

Brittany

so I had my daughter 2 months ago, I stopped spotting at 5 weeks. Me and my husband have had sex but hes been pulling out, except once when he got a little in me, I went straight to shower and trying to wash it out. I'm exclusively breast feeding and was told u dont ovulate or have a period first six months, but the last two days I been spotting brown then a little red then pink then it just stopped. So I guess my questions are can u ovulate and have period even though ur exclusive breastfeeding? Is this still me just having after birth bleeding or could this be something else? Any advice or answers would be great. If it makes a difference this is my third child and I had c-section.
