I agree, you need to have a blood test done. It's very, very possible to become pregnant using the pull out method. It doesn't provide ANY protection, and you're playing with fire if you're not wanting children.
wow. Maybe all the tests could be faulty. Id say best bet is to go to your ur gyno or just your regular doctor and get blood drawn. If your pee sint telling you, the blood will. The test, mind you, works its magic in the wee hours in the morning. the minute you wake up, thats when you take the test. Hope this helps, and get that blood work!
sometimes changing a sex pattern can cause a period delay. if you have normal periods try waiting another week and take another test.
It is possible to get false negatives with the store bought tests, but I definintly think it's the stress causing your lateness.
However, if you're finding yourself staying late, you can take another test a little further down the line, or head in to your doc for a blood test to find out if you're pregnant.
Also, as tempting as it is, you shouldn't have unprotected sex unless you're ready for that baby. Pre-*** has sperm in it as well, and even if you or your partner thinks he doesn't precum, he does.
And besides pregnancy protection, some condoms can also help protect you from STIs and STDs.
If the condoms for sure aren't your thing, birth controls offer many other benefits besides just birth control.
Please consider one, life is hard enough on women today.
Good luck and Best wishes! :)
