In the UK mothers day's the last sunday in March. Last year my Due date was march 22nd, Mothers day was March 26th and DD came on April 1st. DP said "you're not really a mum yet" and ignored it, even though i expressed a wish to celebrate it (was hard too as only the 2nd mothers day since i lost my own mum). Sadly this level of denial (about him being a dad, rather than me being a mum) remained even after the baby was born, which is one of the reasons i left him.

My friend (and birth partner a few days later) got me a card from her and the bump which made me cry.
