This is month 2 ttc and last night I started spotting. Af is not due until next Tuesday/ Wednesday. Today is day 23 of my cycle. Had continued spotting today and cramps on and off. Not sure what this is?!  Also, last cycle, the same thing happened- I started spotting 4 days before af was due, spotted for like 3 days, then bled for 1-2.   Could my cycle be trying to change?  Stress maybe?  Any thoughts?
