Late period negative test

Sierra

My period is now three days late but I’ve taken multiple pregnancy tests and they all say negative every one, my period has never been late before I’ve been trying to get pregnant for a long time now I started to lose hope until this late one but each negative test I take everyday continues to lose my hope now instead of a period though it’s just discharge I thought I would have my period this morning because yesterday there was out of white pink discharge but then nothing today would could be wrong with me?
