And how often is it down to just varying cycle length?
Af was due Monday so tested Monday evening and it was bfn. Now 3 days on and no af and certainly no sign of her.
For the last fortnight I've had incredibly tender nipples that hurt in coldish shower water and lots of white discharge... But no bfp or af.
Last month my cycle was 28 days exactly. Before that I had my usual pill related cycle, I just didn't go back on the pill.
