Early symptoms of pregnancy.

So the first strip was taken on 5dpo then 6,7 2 on 8dpo, 2 on 9dpo, 10, 11 and 12. Taking a clear blue on Friday just to put my mind at ease . I'm on CD30 which at the most ever is 27. Can't help getting excited but my SO keeps telling me to stop thinking about it in case it's nothing. Worse thing is I really feel no different other than have a terrible cold which I don't normally have and a headache which lasted about 3 days which is now easing up. Help and advise is greatly appreciated. Bd to all x
