Stress whats wrong with me?

Ive been wanting to get pregnant for 7 months, now i am 5-6 weeks and i feel unhumanly stressd, whats wrong? feel like givin up already? is this normal, i cant have a general conversation with my boyfriend no more because it ends up turning into a meaningless arguement? im happy to be pregnant and i thank God so so much, i just want to know is it normal? im worried i'll lose my boyfriend because of my hissy fits? every little tiny thing gets on my nerves, someone tapping their hands on a table will set me off. Yes thats how bad it is! Anyone feel the same?x thanks for your concern...
