I am 11 days late for my period im never late it is always on the 15th of every month. I have no syptoms of pregnancy didnt have with first child either but ive taken 2 hpt and they both turned out negative. I had streap throat last month didnot take prescribed medicine could that have made my period miss? Im not stressed or any of the other things people say im just wondering if there is a chance of something else being wrong but all the fourms usually say some kind of bleeding when there is a chance of anything wrong.
