Agree with n2l. The 'average' couple can take 6 months to fall pregnant, so all could be going fine but that 'happy egg' might not be there atm, implantation might be happening or it might just not be sticky this month......sheesh so many things that can go wrong! Its any wonder anyone gets pregnant

For me, AF returned when DD was 3.5 months, has been a 28 day cycle ever since. She was exclusively breatfed and still fed overnight until about 18 months.
