Thanks for your support Indy, I'm sorry you are going through such a confusing time too . I hope your cycle returns to a predictable pattern really soon.

Just thought I'd update and say that I've been getting lots of light cramping all day, each day and the last two days I have been extremely nauseous about an hour after eating lunch, to the point that I have been retching (sorry for TMI!). I have been tired, grumpy (my poor family) and emotional. I've also been madly reorganising the whole house. Whether I'm pg or not, my hormones are up to something very weird...
