cross posted as need advice.
used OPK & got + last Saturday/Sunday, felt sharp twingy/cramps on Monday (so guessed this was O).
that would make me approx 8dpo yesterday. When i went to the loo yesterday evening, i had a smear of bright red stained cm. then nothing more.
today, i've had a little brown stained cm when i wipe. nothing red. have sore bbs, but this could be the case for pg or af!
IS this the start of AF? Very early though? would make for a short lp?
COULD it be implantation bleed?
please share experiences...
