So many questions

Danielle

Please help me understand. What makes ttc while bf difficult? Is it only because it inhibits the return of AF and ovulation? Or is it more than that? I'm 12 months PP, AF returned 3 months PP with positive OPKs. We've been ttc since December. Is this just normal ttc problems or is it because I'm still bf? Also I'm assuming positive OPKs mean I'm ovulating, especially since I think I can feel it, or am I totally wrong?
