From what i know, you still can be pregnant. You can be pregnant and a hpt might not pick it up do to the level of hormones in your body. Just wait it out. When ur a week late try another test and if you still dont get your period by the time your two weeks late get into a doctor to get a test done and find out what is going on. If you ever need anyone to talk to i’m always around send me a message. Keep me posted.
