Could I be pregnant? HELP PLEASE!!

Katie
OK what does this mean? I don't feel pregnant like I did my other two pregnancies a.k.a my boobs arent really sore, I don't have lumps around my nipples,my temperature isn't really  that high like my other two pregnancies, I am getting kind of worried something might be wrong with me, I was supposed to start my period two days ago. I took a pregnancy test on the 23rd because I want to a amusement park The test was negative, I ovulated on the 15th of this month
