How Many Weeks Does Period Start After Breastfeeding On Average, Worried Im Pregnant Again?

I stopped breastfeeding six weeks ago and had intercourse with my husband about 3 weeks ago but forgot to take my pill that day so would have been uncovered. I am getting signs of a period ie, tired, moody, spotty and depressed, could these be signs of pregnancy or definitely a period about to start?

What Is The Average Age To Stop Breastfeeding Entirely ?

What is the average age for children to stop breastfeeding (regularly, and at all) worldwide? How accurate are the statistics available? Thanks!
