pregnant or not?!

So I'm posting this for my friend! She's wondering if she is pregnant or not.. She's 6 days late, she had morning sickness, she's dizzy, she got fatter without actually eating more than usual, she pee's more often then she should, really emotional, a lot more tired, get headaches, her breast are sore, and she gets heartaches.. So I was just wondering if anyone could help?! Would mean a lot, thanks!
