Need help

aurora • I am 28 years old i have been with my husband for 7 years now we recently got married in april 15,2015 i have a 9year old girl with my ex and a 3 year old with my husband!!!
I was supposed to start my period today but I didn't I took a pregnancy test it came out not pregnant but my boobs hurt just a lil they feel tender more my nipple area what does that mean I never felt that with my other two pregnancies and usually I cramp two days before my period and that didn't happen either
