I am actually in the same position as you are. My last cycle started on July 1st and normally lasts about 30-31 days. So far no sign of my period and all the tests I've taken were negative. Also I've tried the dollar store tests, Answer and First response all with the same results. The best advice I can give is to wait a week and test again. If you are still getting a negative test and no period when you are 3-4 weeks late you should call your doctor. In some women the hcg levels take longer to rise, I've even heard of some women saying they didn't get a positive home test until they were nearly 60 days late, yet they had a positive blood test a few weeks earlier. So if you are still getting a negative home test get a blood test! I will probably be getting one myself towards the end of this week
