Last year when I started TTC I found a great website where you could record the dates of your periods and it would calculate your cycle and rough ovulation date (I'm generally quite irregular - one month it can be 37 days, the next 26). You could also record things like BBT if you wanted to help you. I ended up getting pregnant pretty quickly and so stopped using it.
My DD is now 6 months old and I have been EBF up until a few weeks ago when we started weaning, and my periods still haven't come back. I am starting to think about no.2 though so wanted to find this website again. Unfortunately, I didn't bookmark it and can't find it anywhere. Most websites ask you to put in your cycle rather than calculating it but as I tend not to be regular, this is quite tricky. Does this website sound familiar to anyone? Or can you recommend a good one? By the way, I'm still in the dark ages phone-wise so it's no use recommending an app!
