Gah, I couldn't help it. Breasts have been suddenly fuller and more sore since yesterday, I didn't wake with a migraine aura, and I felt peculiarly good despite how stressful and depressing yesterday should have been. Sure enough, test was ultra faint positive again, though within 10 minute window barely with editing. It has dried to a visible line to the naked eye so I've hidden it. DH thinks we had a chemical. I think, if this one manages to stick, I've definitely trumped the rest of his Christmas presents this year...
Not holding my breath though.
