Sorry to be a bore.
I am on day 23 of my cycle. I'm not ttc (although wouldn't be end of world) but we had a contraception failure on day 8 of my cycle and am now feeling distinctly pregnant - strange taste in mouth, nauseous, sore breasts, ravenous. Similar-ish to symptoms of AF but it's the taste in the mouth and the very very sore breasts that are giving me suspicions.
Waste of time testing?
