Had spotting last night after sex and still have a little bit of bleeding and pressure in my vigina from last night.. so I called my obgyn and told them and now I'm going in at 2 to get an altrasound.. they think the baby is fine they just want to make sure... well the bright side to this is I get to see my baby boy!
