Three- test 25 days late

I don't know what's going on I miss my period for 25 days I took two test two weeks ago then I took a test the other day and all of them are negative. I can't go to the doctor and take a blood test because I don't have a doctor right now my insurance is all messed up. I dont want to keep going on like am I pregnant or not. So I guess I'll go back to trying to loss weight.
