I've only just (in the past week or so) realised what BH feel like for me. It's such a subtle, slight feeling that it's very easy to miss. Most of the time I don't realise they're happening, or I have to double check by prodding my belly to see if it's gone rock hard. Is it normal for BH to be such a slight feeling, especially this late in pg? I have noticed that I'm getting them more often now, but it's still only a very subtle feeling.
