Period when pregnant?

and was eating much more. i wake every night with cramps. and one day my stomach was going through alot of noises and stuff and every time i ate it would hurttttt. i had nausea only a little, crampy, weird dreams, sore boobs/nips, veins ect. when expected ovulation came again i didnt have any EWCM (egg white cervical mucus) . i continued to check and it was sometimes creamy or thick/tacky always white but never stretchy. well my "period" came 2 days early so i thought but it wasnt my usual 7 days it was maybe 41/2. tmi but it started pink (scant) then dark red (heavier flow) and then brown (spotting). i was shocked but decided to wait to see if i missed this period and while waiting still prego symptoms are here including itchy nips and swollen boobs. period came so i THINK but this time started brown and now dark red. im so confused. maybe im crazy.......anyone?
