NOT GETTING MY HOPES UP

So I'm 13 dpo and AF is supposed to come in 2 days......every other time I tried at this time I would be passing creamy CM and I'm not....I'm very wet..but of course I'm cramping some to and have gas.....a but moody...havent been sleeping good...backache when I wake up.....boobs have these sensations here and there and every now and then they are sensitive.....I've been having some anxiety attacks for the last few days and I take meds for it but the meds dont seem to be cutting it....of course constipation.....I dont like to spot out things because AF always ends up coming but something I found very strange is I love water and I only drink bottled water and I drink the same kind but for the last few days the taste has just seemed off to me it has a different taste to it...I dont know if it's just me not really being thirsty for it are it actually has a different taste.....
