Aw, totoo na worrying yan mama, lalo na kapag delayed ang regla after nagkaroon na! Sa pure breastfeeding, it's actually common na walang regla or very irregular pa dahil sa hormones ng breastmilk, kaya kahit nag-appear once in October tapos nawala ulit, it can happen, pero para sa peace of mind mo talaga, better to check with your OB kasi mahaba na talaga from November to now, at sila lang ang makakaconfirm kung anong exactly ang nangyari after that intercourse. A few of us moms sa group din nag-experience ng weird cycles after giving birth, at isa-arrange lang ng OB properly once na-checkup, so don't worry too much na, mama, isang quick visit lang to rule out anything!
