MENSTRUATION CS MOMMY

Mga CS mommies,,, question po.. I gave birth last feb 22. Then ngka period aq april 27 til Jun 3. So its 7 days. I am pure breast feed. Supposedly may mens na aq ng May 27, right? But as per google,, may mga times daw talaga n umaabot ng 21 to 38 ang cycle. Today marked the 7 days delayed from may 27. Ng PT aq 4 times, buts its negative. My question is may irregularities ba talaga pag Cs ka? Or possibility na preggy aq? Ps: withdrawal kami n hubby. Once lang may nangyare before my expected mens ng May 27.
