Not happy!

I ovulated a few days early this month (yeaterday) and when i told my oh we needed to do the baby dance he went 'oh erm i did some 'DIY' this morning'. Grr i was not happy! He took it as when i said he needs to keep a fresh supply during my AF he thought i went all month long then had a go at me that it was my fault the dates were wrong. I wish they'd give men lessons in how a woman's body works.
