Last month I had two periods. Which is wired because I am usually regular on the 15th of each month. Well in October I had one period on the 4th and ended on the ninth. Then I had another on the 15th and ended in three day. Well this month so far I have had nothing. I took pregnancy test and on one test I saw two lines but one line was super faint and the other came back negative. My breast and nipples are sensitive and I am nauseated through the day. I was dizzy yesterday and I have become more tired. Lately though as well I have been having this bad cough do you think that is why I haven't gotten my period this month or should I just test again at the end of the month if I don't get my period. Thanks y'all
