period question for those EBF or EP

After getting your period the first time post partum, did you get it regularly after that?  I am EBF and got my period 12 weeks pp. My cycles are 32 days so I'm due soon, but I'm worried that cycles will be irregular due to breastfeeding and ovulation day will be off. How were your cycles?  We had an accident (condom broke) and now I'm worried 😩.
