pregnant with first baby

this is first pregnancy and with my calculations im only 6 weeks.

i have had nausea majorly tired and moody

last i guess week off and on been light cramping is there anything to worry about since cramping comes and goes there is no blood

i don't sleep at all i pee all night long

i will be seeing about getting obgyn in about a week.

any comments or advice to assure me every thing is ok i been looking at the web and ectopic pregnancy and miscarriage is very scary to think of
