Okay I know 5 now 6 days isn't that late but for me it is and has me thinking. Ive been on the pill the past year and take it every morning religiously. I haven't started my new pack yet because my period just didn't come like normal. was due on the 19th and have had the usual pre symptoms but each time I think it's coming it's just not there. Getting anxious and frustrated now.  I have been more tired I've noticed but for me that's not too alarming because I do work some night shifts during the week. I did wake up this morning around 6 when my SO's alarm went off and I felt like I was hammered drunk (dizzy) which I definitely was not and went back to sleep. Felt fine after I woke up around 10(my day off so I slept late).
