Trying for number 2

Anyone having issues or had issues trying for number 2?  I turned 38 today.  Had no problems with number 1 at 34 and number 2 just doesn't seem to want to happen for me.   We tried for over a year and took some time off.  Started trying again and still nothing.  My period is due today and I've been spotting since last Thursday.   That to me is odd in itself.
