Sarah...What you've 'heard' are what used to be referred to in the 'old days' :-)
as old wives tales. Our first 2 sons were close together like that...I was
extremely nauseous with our first...and just breezed through the next 2. So
it's hard to say. It does NOT mean anything is wrong.
Try to relax and enjoy your babies...they will grow up before you know it...to
drive cars...and do all kinds of other things that will quickly turn your hair
gray. Savor the moment...these are priceless times for you! :-) kathryn
