Be careful what you say!

I went through my second mc on Sunday and it is hard but I am ready to try again.  Last night my dad said to me while I was having a glass of wine "thank god you are not stupid enough to try and get pregnant now".  We told a few family members the last time but we kept this one to ourself until we got further along.  We didn't get a chance to announce it.  Why is it any of his business sorry just had to vent!
