Starting to Have Doubts

I am starting to have doubts that conceiving a second child will be any different than it was with conceiving Micah.  My cycle has changed to 26 days instead of 28 days.  I don't think the shorter cycle is anything to worry about, because I am 99% sure I am ovulating on day 12.  From what I have read that would put the length of both phases of my cycle where they need to be.  It also gives me more chances of conceiving each year.  I'm somewhat thankful, although disappointed, that we didn't conceive in March, because two of my friends just experienced miscarriages.  My heart is broken for them.
