A week before my period was supposed to start (April 16) I had terrible cramping. I did research on implantation cramping and after a few days it went away so I figured it was just early period cramps. My boobs hurt, I have an enormous appetite, and still have slight cramping. April 16 has come and gone... Here we are, April 20th and I still have nothing. My periods are always 28 days apart... It’s been 33 days. I’ve taken at least 9 pregnancy tests (all sorts of brands) and they’re all negative. This hasn’t ever happened before and I don’t know what to think... What do you think?
