No period while breastfeeding?

Ok so I’ve been breastfeeding for almost 10 months now. Last month Was my first period which started 5/25 and ended 5/29. Now this month I keep feeling bloated, cramps and lower back pain but no period. I’m not sure if I’m going to get a period again every month from now on?? I’m not on any birth control. Hubby uses condoms.

Has this happened to any other mom? Like does your period come and go cause your body is trying to get back on track? I’m just so confused 🤷🏻‍♀️
