Looking for advice

Liz • Late in my child-bearing years I have met the love of my life and we are so eager to become parents.
Been TTC for 4 months, AF due 30/11. This morning I started bleeding but thought 'that's cool I'm ovulating'. As the day has gone on its got heavier and tonight I have pains too. I've never experienced mid-cycle bleeding/pains and am concerned a little. What do you guys think?
