excited!

Michelle
I'm so excited and I'm much disbelief that I've been taking a test almost everyday just to see if it's still positive. I have so many emotions and we've only told close friends and family. Today I'm 4 weeks. :)
We had been trying to conceive since last January!
Symptoms I'm feeling: very very light cramping, no spotting, short of breath all day long! Hungriness and this weird feeling of something in my throat??? Nausea? Haven't thrown up but Not sure what it is but it's irritating. It doesn't hurt it just make me feel sort of uncomfortable. Bloating since day of conception, and sleepiness. 
Any ladies feeling the same this early? Anything different.
