Cycle day 50 & still no period-Periods all over the place since stopping breastfeeding

I stopped breastfeeding in August 2020 when my little girl was 13 months & got my first period in December 2020 (hadn’t had one since before i got pregnant) & then got my 2nd period in January 6 weeks later & now nothing since but showing all the signs of coming on!

Could my body be trying to Adjust still because of breastfeeding for 13 months?

I had a blood test in November to check my hormones levels & the results all came back completely normal.

Anyone else experienced this when they have breastfed or have any advice please? X
