Some people told me that when ur pee is very yellow it contains more hcg..Is that true? Or it doesn't matter at all..I am one week a two days late..My breast are beginning to get sore..But not too bad..They seem fuller..But i'm not sure it's a preggy sign...Anyways..I tested one morning and my pee wasn't even yellow at all..I got a neg...Does it matter? If my period doesn't come next week then i'll probaby have to test again...
