Usually after implantation (7-12dpo). But lots of people dont have any symptoms till weeks after AF is already late.. By lochia do you mean implantation spotting? that would also occur between 7-12 days post O as well give or take a little sometimes
what is lochia?
with boys I had symptoms way early
with the girl I thought something was wrong - no symptoms till 9 weeks
lochia is the discharge you have after you have a baby
The earliest I had symptoms was 12dpo, I started getting queasy with certain smells. A couple of days later the sore bbs kicked in.
