Period After Giving Birth

Hi mommies. I gave birth during May 12th and my lochia ended around week 7 and immediately after that my menses came. (so there's no pause at all even for a day) I bled for 2 entire months and it after 7 days of menses it stop. Then menses came again another another 7 days.. And stop after 7 days. And now today it came again. Should I be worried? I fully dl on demand and also pump.
