Hey mama, I understand ang worry mo, that's a lot happening with your cycle and the timing! So based sa experience ng iba, sometimes when you take pills late or irregular ang intake, it can really mess with your flow, mas maikli, lighter, walang usual spotting, but pregnancy is also possible given that high-risk window you mentioned on Dec 24. Since you're noticing changes na unusual sa pattern mo (ang dami ng days, walang spotting), I'd really suggest getting a pregnancy test done or checking with your OB para sure na, kasi hindi lang cycles ang affected but your peace of mind din, alam mo? Don't stress too much in the meantime, maraming mommies namin nag-experience ng irregular cycles from pills or stress, pero better safe than sorry with this one!
