Ramzi please? And a tmi question..

Casey
I went to the ob today thinking I was 7 weeks 3 days and based on my ultrasound I'm only 6 weeks 2 days:( oh well same thing happened with my daughter and she came early anyway. Can anyone tell the gender prediction by the ramzi method? 
Also, has anyone had horrible diarrhea?? Sorry, tmi, but I feel awful! I have felt morning sickness and nausea all day, then have started having diarrhea:( lovely symptoms!! Thanks for any info!!
