Breastfeeding and delayed period 🤔

After having my baby in May, I have had pretty regular cycles, about 33 days in between with the very first period starting in September, which was the longest cycle I’ve had so far with a length of 42 days. This month I’m on cycle day 46... Firstly, I’m just wondering if the length of my cycles are considered normal after having a baby. Secondly, I know while breastfeeding it’s common to skip a period, but with my cycles being pretty regular for the last 5 months I’m wondering if it’s still common to have a delayed or missed period. Any breastfeeding moms going through anything similar give me some feedback I’d like to know! Thanks in advance 💕
