Pure guesswork here - but I've just started my first AF since DD2 yesterday and I have been feeling it almost coming for a couple of months - would bloat, cramp horribly, gain a kilor of fluid on my stomach, pain in my bladder, nauseous, (panicked I may somehow against all odds be pregnant a few times with that list) then DD2 would be sick/teething etc and start feeding even more and it would hold off. Finally I have a lame attempt at an AF - all the above, but very light, more like when I first started cycling as a girl. So, I am assumming that BFing can indeed impact on your fertility, ovulation and regularity because I can feel it doing it to me. ??
