Ectopic pregnancy?


I’m a few days late on my period and am getting mostly negative tests (I had two super super faint positives). I have so many symptoms of being pregnant; sore breasts, breast changes (darkening and Montgomery tubules), nausea, migraines, dizziness, stomach and back cramps. My question, is it possible to be having a tubal and get negative tests this early because of lower hcg? Any experiences with this?
