Anyone else have this happen ?

OK so I am currently 2 days late which I have been before. Last month me and my husband had sex often! My last period was October 8-13. A few nights ago me and my husband had sex and I spotted pink after, not really sure why bc I never have before. About 2 weeks ago I had period cramps, bad mood almost everyday, I still get bad heart burn almost every morning, back aches, random pains on my left side or right never at the same time, in the middle, and I randomly start feeling naseaus. I tested this morning with pink dye test and I'm almost sure it was negative. I tried the digital couple days before period was due and it said not pregnant. I usually have period cramps a day or so before my period which I haven't expierenced yet, my mucus is pretty white I feel tightness hear and then but that's about it. Sorry for the paragraph hopefully I get more than enough people to comment (: thanks to those who do! Helpppp please my husband thinks I'm nutts so I have no one to talk to about this ! I have been feeling depressed!
