I am eleven days late I took a pregnancy test and it was negative What should i do next?

I myself am 9 days late as of today, I took a pregnancy test 2 days ago that was negative. It might just be too early for the test to catch it, or if you have been really stressed that can cause you to be really late, it's happened to me before. My advice, just don't go drinking or takin any meds that pregnant women shouldn't do, and wait a few days then take a new test, and if you can do it in the morning. Last time I got pregnant I was only a week late and I took 3 tests within like 5 days, first 2 were negative, the third one I took in the morning when I first went and it was positive.
