My last period was july 9th. I think I'm a little bit of a lot late! My last 3 periods are as follows... May 13 june 9 july 9, if you would please do the math u would see I normally get my period 1-2 days before or 1-2 days after the "28 day cycle". Which means I should have gotten it between the 4th-8th of this month. It is now the 21st and still nothing. I took a test 7 days ago but got a negative, idk if it was too soon to tell, or there is no baby there.plus the fact that they were from the dollar store. I have never missed a period ever since I was 11, I am now 19, so idk if I am starting to miss them now, or I may be pregnant?please help me out, I would love to know if there is a bun in the oven or not
