Anyone else irrationally upset after not getting preg 1st month?

It was just our first month of trying... I didn't even really want to be pregnant yet because there are so many events coming up this next month... We didn't really try THAT hard... We were only "not preventing" not really "trying"... So why am I so upset?
​I told myself I wouldn't feel this way. That it'll happen when it happens and when it does, the timing will be perfect. 
​But I had all the symptoms... Late period, sore boobs, massive bloating, headaches, nausea... All of it! How can you have all these things and NOT be pregnant? 
​I know it's irrational and ridiculous to be upset after it not happening the first month, but that's not stopping me from throwing myself a little pity party. Anyone else with me?
