I went and got a blood test done at a clinic and the nurse told me it was neg. I showed her my home e.p.t. tests how they came out pos and she said that the e.p.t. is.more sensitive then the tests that they do so I might be too early for there tests to pick up on and to come back in if I don't get my period in a week. I called them to ask my levels because I forgot to ask and the nurse on the phone said they don't run level checks on blood pregnancy tests
