I had a blighted ovum in April of 2007, a chemical in April 2008, and finally conceived in October 2008 and had a normal pregnancy with delivery in July 2009. I am currently 7w6d with a lil Butterbean and all I think about is another blighted ovum or a spontaneous miscarriage. Had u/s at 5w4d and checked implantation. Saw gestational sac. Went for another at 6w2d and saw and heard heartbeat of 129 bpm which doc said was good. Despite this, I am constantly feeling like the next time I go in the heart won't be beating anymore or there will be another blighted ovum. I keep reading too many horror stories online. Someone have any tips to reassure me? :(
