Breastfeeding and pumping moms! I have a question for you!

So, I exclusively pump and got my first period in August. According to Glow (going based on my old cycle length) I'm currently 12 days late. I used protection each time we had sex so this isn't one of the am I pregnant questions. My question is for the ones who got their period did it come again the following month? If it did were you on time/late/early? If it didn't how "late" are you? With my other children I went on birth control right away so I have nothing to compare this to. Any help would be greatly appreciated! Thanks ladies!!!
