It is still only a few days after your period should have started, and remember, you can get a false negative while false positives are highly unusual. My advice would be to wait until after the weekend, so, say Monday, and if you still haven't got your period then buy a 'high-end' pregnancy test and see how that comes out. HPTs do vary in reliability and you may be using a less reliable brand, old tests etc. Good luck, it could be your time!Help, advice please, could i be preg?
All I know is that it takes 3 weeks after you made love for the test results to come up. Because after 3 weeks, your hormones come about and prove this on the test. So just see a local doctor and ask these things::::: Everything happens for a reason.
