I have a question... well I guess that's obvious huh? Well in September my period was somewhere around 2 1/2 to 3 weeks late I took 2 pregnancy tests both come up not pregnant. I got my period on the 7th of October. But I put that one off as stress due to my aunt having just passed away. This month my menstrul calendar said my period was due the 14th well it's now the 27th and it still isn't here. I haven't taken a test yet because I thought I should wait until later to see if it will come.this month I haven't been under any stress other than normal stuff for this time of the year. Before the September period I had very regular periods always within like 2 days of when I should have them. I also haven't had any signs of a period other than maybe my moodiness. Granted yes my husband and I are trying to get pregnant, but with my periods being so off I'm starting to wonder if it will be possible. What reasons are there that my periods could be so off? And overall what advise can you give for this situation?
