How big is the chance of still getting your period?

Your belly can also be sensitive because you're pregnant; your uterus is also preparing itself. It's really hard to say what your chances are of still getting your period since you're so early in your pregnancy. Try to enjoy it and not dwell too much on the thought that something might go wrong. As long as you're not bleeding, things are generally okay. I hope you'll see a beating heart in a few weeks, and then the uncertainty will decrease too.

Hey, I read your story.
Can I ask which tests you used? Because I’m supposed to get my period next Monday but I can’t wait that long. I don’t know which tests are reliable enough to use before the expected date. I’d love to hear from you!

Klaravs, most brands say they're reliable from the day of your expected period. Testing earlier is possible, but then you really need to do it first thing in the morning with concentrated urine. If you still get a negative result, it might just be too early. If it's positive, there's a good chance you're really pregnant. I understand you want to wait, but just be patient for a bit.
