its been a year.....

been trying to conceive for almost a year, still no baby :( af is due aug 7 byt lately been peeing way more than normal, very tender breasts for over a week. had a lot of dizziness a few days ago, and I just feel pregnant. I had a son in 2010 and I didnt know I was pregnant till 4 weeks in. had no symptoms no missed af at first. im just really hoping it stuck this time! I dont know if I should wait for af or just take a test because im really excited but I don't wanna be disappointed
