Went in today to see dr. Was having some light spotting. I meant very light but hey it was there and I freaked. I'm 6w5d hb was 128. Dr says hb was very low and my yolk sac did not look as he would like it too.... Any experience with this?? Anyone??? I'm an emotional roller coaster... As of now baby is alive but he said things are negatively adding up. How can I sleep??? I'm sick to my stomach about this.
