I have not been on my period since the end of October, my nipples have been sore for awhile now but they are not as bad as they were? I have been getting cramps as though i was coming on my period but nothing, today i got cramps and now am spotting? Besides October the last time i had intercourse was last week.

My lower back hurts,certain smells irritate me. the thing is last week i was so sick, i had something like the flu. I had the diarrhea,throwing up,fever,chills,aches... but the symptoms only lasted one day?

I took 2 pregnancy test and both were negative? Could i be pregnant and it just not show or is something else going on? Please help. I made an doctor's appointment, i just want your thoughts?
