If you stopped your grandparents from meeting, do you think
You wouldn't be born
Or you'd be born but with different grandparents?

So here's the thing. Time travel as it's been shown in popular fiction isn't possible. That's not to say time travel itself isn't possible, but the whole grandparents paradox wouldn't be a thing, and here's why.
When you travel back to a moment in time, you're not actually in your own past. What you've done is created a parallel universe where that moment is occurring right now. What this means for the casual time traveler is that you can fuсk with anything you want. You can unalive historic figures, save historic figures, be the one to personally put Hitler in the ground, but if you manage to make it back to your current time, nothing will have changed. And so in the end, the only use for time travel is to see how things actually were back in the day.
TL;DR: Nothing would happen to you.
