You usually get pregnant/ovulate 2 weeks after the start of your period. If your timing is accurate, you're probably not pregnant. Also, implantation bleeding is almost nothing. I've been preggers 4x and I've never even noticed implantation bleeding. You can take a test 5 days before you're due to start your period but take a digital test because the lines on the other tests are so faint that it looks negative. The digital test will show up yes/pregnant or no/not pregnant. Good luck!
