Omg my mind is all scrambled

i need some help, i can not tell if i could be pregnant or im hoping a little to hard all the stats point to pregnancy but it could also be that i want a pregnancy so my mind is playing games on me. Here are the stats lol! my last " real" period was oct. 30, 2009 then i had an irregular period nov. 25, 2009 ( my suspected ovulation day was nov. 14 on which me and my husband had sex and the day after the 15th) i say my "period" was irregular because one it started off very minuscule i wouldnt have known until i wiped. it was discharge with pink specs and brown. and it stayed like this for the remainder of nov. 25 the next it became slightly heavier and i noticed bright reddish coloring the flow was pretty light for what i am used to i usually bleed pretty heavy, this flow was light to med. and required a pad for a light flow. after 4 days my "period" was over during this time i had alot of pregnancy symptoms severe bloating to the point where jeans and work pants were very uncomfortable to wear, had some abdomanal cramping, slight headaches, breast tenderness but it wasn't severe only wen i touched them in certain areas would i feel tenderness, and i had nausea alot in the afternoon while at work. these symptoms started to go away and are now coming back as of today dec.22 i experience occasional nausea, slight cramping and fluttering feelings in my stomach, growling noises lol even after i eat a meal the sounds just come randomly lol. also i have been very gasy sorry for tmi but no headaches or backaches or breast tenderness yet. tracking my cycle i was supposed to start on or around yest. dec 21 but i am or could be one day late for my MC. could this be a positive in the making ( i took one Preg. test on 11 of dec. came back neg.) but i could have tested to early. what do you guys think? any suggestions experinces would be greatly appreciated thanx im wrecking my brain lol!
