I've never hoped for a negative test before but cross your fingers for me! The Dr. called to say that my Rh blood work is negative (85% of knocked up women usually have a positive reading). This means if Mark's is also negative than my body won't try and attack Tomato as it's likely that Tomato's is also negative. If Mark gives us a positive result, then I get big shot in 9 weeks time. It's nothing to worry about really.
