It is possible you had mc without knowing you were prego it happens alot and is the most common type of mc. Was it heavier than normal? If you are concerned about it bc you know your body better than anyone, i would make Dr appt. If your cycle is really crazy now and normally pretty regular then see your Dr. Normal cycles are 28-35 days they should not be longer than 35 days.

It sounds like your has increased its length.  This could be due to a number of things, including stress, health issues, weight gain...Our bodies are funny things.  If you're getting a BFN, then you most likely are not pregnant.
