Late period

The first day of my last period was May 7th and it lasted 5 days as normal. My period is now 2 weeks an 2 days late. I normally have pretty regular periods (within 5 days of my estimate next period) so this is odd to me. Anyways, I don't know if I have been experiencing any pregnancy symptoms or not. Just recently I have noticed I been using the bathroom a lot more (like once every 2 hrs) give or take. I have these sharps pains in my lower abdomen that come an go. And I have been feeling more tired than usual. If I were to be pregnant, what are other symptoms I should be experiencing by now?
