Hello ladies need some advice been trying to conceive 8 months now given up using opk tests just hoping it will happen when time is right.

Last period 19/09 I have dead on 28 day cycle

Only done the deed on cycle day 18 as hubby away. I don’t know what days I ovulate

I am 7 days away from the witches arrival and this morning had light pink spotting only when wiping (sorry tmi) few cramps and now turned light brown and hardly anythink there.

Could this be implantation?? Or just my body messing up lol
