Hi, I have just had my first loading dose of B12, and started my period yesterday, normally I hardly notice these but this time I have painful cramps and am a lot heavier than usual.
It could be anything of course, but wondered if this is normal on B12, or when you first start?
also am feeling super rotten today, finding it hard to catch my breath, lots of aches - I think a lot of people fel tis way on their periods, I have heard all sorts of tales over the years and thought myself lucky to have really easy ones.
