Ay nak, na-relate ko talaga, three years ng breastfeeding pa lang din, kaya ang irregular period mo ay very common pa rin talaga, lalo na if your son is still nursing frequently. Pero honestly, eight months without a period then super tipid na flow is worth checking with your OB para ma-ease ang mind mo, a few of my mom friends din nag-worry about the same thing and after checkup, lahat naman okay pero at least na-confirm na, so makatulog kayo ng mahimbing. It could be the extended breastfeeding, hormonal changes, or something else, pero mas better safe than sorry talaga, lalo na if it's so different from your usual cycle. Don't stress too much muna, go book that appointment and let your doctor put your mind at rest.
