TTC and AF due on October 20th

Liz • TTC baby #1
Recently newlyweds and want to start TTC!  AF is due October 20th and just wondering if anyone else out there was on the same schedule! Advise is welcomed! I am ovulating today and noticed light spotting of pinkish and brownish blood... Tmi sorry! I haven't bled like this before but I read that it's because I'm ovulating! Any input would be helpful and of course buddies!
