So as of today I’m 11 days late and I’ve taken two tests with 3 days between them and they both are negative. I don’t know what to do. I’ve had no spotting, or anything, the only thing that had made me a little concerned is my boobs are swollen but they aren’t tender to touch or anything. So I don’t know if I should be worried if I’m pregnant or worry about something else? Any thoughts? Thanks!
