I met up with a friend last Tuesday, who told me she'd been nauseous that morning, but by lunchtime it had passed.
Then this morning she rang me and mentioned that she's having vv light menstrual bleeding and minor twinges in her womb - but it's not a period as she was ovulating on Tuesay (nausea day).
I have an idea of what the cause could be...what do you think?
