I've only had two periods since ds was conceived as I was bfing... I had one a couple of months ago, pretty light, only lasted a couple of days. Then 27 days later I had another one, slightly heavier and lasted four days. Couple of weeks ago it was my birthday, a sunny day, dh and I had a nice lunch and a bottle of wine together while ds was at the cm... and one thing led to another. It was the first time in absolutely ages. Now I'm on cd 28 and absolutely no signs of the start of my period. I've never had a period longer than 28 days... never. But perhaps my cycle's changed since having ds. I just assumed it was the same as before as the two periods I have had were 27 days apart.
