Some signs but BFN :(

I need help! I've been more tired than normal. The last couple days I have been waking up with a sour feeling stomach. I wouldn't really say I was nauseous but more just had a stomach ache. Today I woke up and my stomach hurt more than it ever has. It went away after I ate but now it's been off and on all day. Seems more of a naesous feeling now. My CM has been irregular. Some days it's dry some days it's creamy. This morning I was getting ready and had a weird dizzy spell. About a week ago I was having cramps like AF was coming but no cramping no and no signs of AF coming. I took a test but was a BFN. I was suppose to get AF today. I'm about 14 DPO. Part of me feels it's not my month but these symptoms are giving me a little hope (I hope they aren't in my head) what are your thoughts!?
