Could i be pregnant ? or is it just in my head becauae i want to be soo bad.....?

I am currently 11 days late for my period. I took a test when I was 4 days late and it was negative ( took in the afternoon ). Last week I felt nauseous when I woke up some days, smells would bother me, even the cleaning supplies they use at wrk made me sick. Been super bloated, can get enough sleep (which sucks since I have a 4 yr old and wrk full time), had cramps like period was coming but still nothing, breast are a lil tender but my nipples feel irretated at times my bra even rubbing againt is irretating, feel cranky all the time, hungry seems like all the time and peeing more than usual... can somebody please give an opinion and keep the negative ones to your self please!
