last month AF came in 15th of February, 3 days late
the month before on the 12th January
Before that always on the 12th for 6 months

No AF yet and its technically the 14th now.... hmmm when would it be due if my cycle is 28 days usually? or is it?
Any advice

Im still breastfeeding and my nipples are quite tender. Would that be a sign?
