Ugh this ttc is killing driving me crazy

So here I am again. Confused like I don't know what. Last month I swore I wouldn't try to worry about testing and driving myself crazy.  But I just checked my cm and it was soooo creamy like never before. Also my boobs are HUGE (I'm normally a A cup but I just got fitted for a new bra and I'm a small C big B) which I'm so excited about lol. But my boobs are killing me. And this past wkend I couldn't handle any of my favourite food (Greek food, huevos rancheros) I got really sick and was a prisoner of the bathroom all wkend. I took a test last wkend and it was negative... According to Glow AF should be arriving in 4 days....Idk I don't want to be disappointed but why am I having all of these pregnancy symptoms????
