yes my gynae told me if never FULLY dl, meaning u pump, or supplement with FM, AF will return much earlier, as early as 4 wks after your deliver. i think mine came back 6 wks after i delivered. i say "i think" cos up till now, i'm not entirely sure its my AF, cos its somewhat different from my previous AF. firstly, my lochia didn't fully clear before i had fresh red bleeding, the lochia was slowly clearing to a watery light brown discharge, then suddenly, on V-day, i had fresh red bleeding. This bleeding didn't smell, unlike lochia which has a stale smell, so i didn't think it was lochia. Anyway, the bleeding suddenly got even heavier 4 days later, n i had AF cramps 6 days later. i bled fresh red blood for 12 days, n up till now, i still have bloody discharge. its been 2 whole weeks! i'm so confused. but i figured since we just gave birth, it is normal for our AF to be abnormal when it first return.
