breastfeeding and periods?

So I had my son in October 2016 and had my first period in January and have had them every month since. But this month it's running late. It's about 3 days late now. Has anyone had their period come and go with breastfeeding? I'm pretty sure I'm not pregnant. My husband and I barley have time for sex and when we had sex it was on low risk days.
