QUESTION!!! Here is everything that has went on...could i be prego or N0...?

Like u I was supposed to start on the 9th and still no period.. I have taken two tedts one walmart brand and one dollar store brand and both were negative.. have same symptoms but no extra bm and this morning while brushing my teeth, didn't eveb get to my tounge before I was gagging and actually got aick from the taste of the tooth paste which has never happened before. We really want to be pregnant and seeing negative signs is a lil depressing.. I will wait a few more days and if no period I will test again woth a better brand of test.
