Does anyone have any similar experiences? Does anyone know what could be causing this? I gave birth to my ds in mid November 2006. Usual 4 ish weeks of lochia, but nothing since. I am 100 per cent sure I am not pregnant again. GP told me not to worry for another few months, then she will do a blood test(?) My periods were never regular but longest gap between them before was 12 weeks, and ds is 25 weeks old today.
