None of those are pregnancy symptoms...

And if you were it would be months before it would be possible to even feel it. Here's a chart why you won't.

You have bigger chunks of corn in your poo than a fetus will be at 6 weeks... can't feel that either.

How late are you for your period right now?

If its not been two weeks then its too early to test.
