I have basically the same question but slightly different! no answer yet :'( But you could have tested at the right time....I had the same problem about 2 months ago. I was so paranoid that i was pregnant! Had light pink spotting even in my boyfriends bed so HE started worrying lol. Talk about stressing. Don't worry though you're most likely not. But you should take a test next week and if still negative believe that your not or get a check up.! :)
If you had unprotected sex then yes you could be pregnant!! You also tested way too early. You should test either after a missed period or two weeks after sex. So the earliest would be the 26th. Good luck!
it's very unlikely that you would get pregnant that day you finish your period. This is because most women ovulate mid cycle, so you're still a week or so offf that point when you had sex. Right now, you're around the time of ovulation which for some women, some times, can cause spotting and light cramping.
You got a negative result because you tested too early, and because you're not pregnant. For you to become pregnant you would have to have sex round about now, and even then you can't test for at least 2 weeks after intercourse. Relax, you're not pregnant.
