I can't stop smiling

I can't stop smiling! I took two pregnancy tests earlier in the week, probably earlier than I should have, and it was a negative. But I have been feeling gross all night and day today so I decided to take one more. But assuming it was negative I got in the shower, but when I got out there were two lines! I couldn't believe it. I thought it might be false because it had been longer than ten minutes. But I was still excited! I didn't have anymore pregnancy tests so at midnight my fiance convinced me we should run to the store. Well I drank a little and was finally able to take the test and it's very faint but there are definitely two lines! At least I know I feel crappy for a very good reason.
