Feeling discouraged...

Yesterday I was 11DPO and I feel pregnant.. I have been sneezing, feeling sick randomly, cramps on one side, acne(I never get acne) major fatigue... I went to bed at 8pm and slept till 10am.. That's not me at all! And I'm not really hungry but the opposite. I've been getting full fast and having a gross feeling after I ate almost like it made me sick. I even dropped two pounds.  I am Italian and trust me I love my pasta😂.. So I took a test yesterday and it was a BFN... Now I just don't even want to text anymore. I feel like I'm out. I don't have sore BB at all.. Like not even the slightest.. And right now I just have a major headache on my temples that won't go away..
