Am I the only one...

My husband and I are trying for our second child. We were able to conceive our daughter in about 3 months. We are in month 2 with trying for another. I swear every little thing has me thinking I'm pregnant. I even have bought a few tests with just the slightest thought I might be, even when I knew I wasn't. I swear I'm driving myself crazy. So the last few days I've been super tired & I cried like a baby yesterday when at a cemetery where my loved ones have been buried at for years and which I've visited several times. Today I'm spotting some and I'm feeling cramps. I want to rush home and take a test but I know it's too soon. So who else drives themselves crazy with the slightest signs????!!!???
