Short Cycle

I am a 30 something female who is trying to get pregnant.  I have been of BC for 10 months and nothing is happening.  I have noticed that my cycles are getting shorter each month.  My last cycle which started on Saturday Morning was gone by Sunday morning.   My ob/gyn has stated this is normal but I am not certain.  I have had my thyroid tested and that came back normal.  Any suggestions?

Your cycle is the time between periods. So by cycle you mean that your *period* is lasting a shorter and shorter amount of time? If that is the case, YES it is normal! You can have a period for ONE day and it's still normal.
