So today by my lmp and ov strips etc I would expect I should be about 5 weeks pg. I have done a clear blue digi with weeks indicator yesterday and today and both times it's said 1-2 weeks! I'm really concerned now that somethings wrong and my hcg levels are not as high as they should be as I should surely be at the 2-3 weeks stage at least? Has anyone else used these and they've been completely wrong, before I drive myself insane.
