Frustrated and confused

I'm 32 and my husband and I have been not doing anything to prevent pregnancy, but haven't been trying hard either.  We both want a baby together (2nd marriage and we both have children from our previous marriages).  But we've had several miscarriages and I don't get it because I had no problems when I was married before. 
 I've been tracking my cycles but no matter when I think I've got it right something seems off.  I Ovulated this month and DTD every other day of my fertile window and ovulation day.  Now, two days after I wake up to EWCM...just less stretchy?   
I think I am driving myself crazy... Last night I dreamed I went for an ultrasound and I saw a perfect little baby spine but the doctor kept telling me it was talapia bones....
