Ren,

You and bubs will be fine! I have had 4 lots of spotting which stresses me out to no end! I went for my 13 week u/s on Monday (after ANOTHER spotting episode on weekend) and the bub is healthy and correct weight and size and the little heartbeat was cruising away! So one day of stess is not going to hurt you guys one little bit! Take from the expert!!
Hope you feel better!
Kate
