I got pg first time with both my boys too - boys just see easier LOL. Think of the 7th month as a sign that you are evading to pink as you would normally be pg with blue by now.
Not really sure how long to say I have been TTC as it is a bit complicated with DH away and moving country soon (so couldn't TTC if it meant not being able to fly). Been on diet since sept, chemical in October and no decent attempt since - hoping April will bring DH and I together in time for O.
