Late period

Kristi

My period is 11 days late. I’ve taken multiple pregnancy tests and all came back negative. My period is never this late. 4 days late at the most. I have no symptoms of anything. The only thing I have out of the normal is acid reflux. I don’t know what else it could be besides pregnancy.

Edit** When I take my bra off at the end of the day, my boobs feel sore.
