Your period just might be off that's all. I think in November there is an extra week or something and it throws a lot of people off!
Good Luck!
just keep trying, it maybe to early to show up, i took 4 all negitive, then bout 3 weeks later 6 came out positive, keep trying lol good luck
It still may be too early for the tests to pick it up, so I would just say to wait a couple more weeks and then try another test.
Your mind could be tricking your body into thinking you're pregnant
Try the first response tests, or just keep waiting. One or the other will show up sooner or later!
