today, thursday i am 4 wks 4 days pregnant, from last period, my hcg levels this morning were 2500, last night they were 1700, and monday 560. today the ultra sound showed a sac and yolk sac but no "peanut", no fetal something, i think a fetal stem, level with me, with hcg levels that high, they should be seeing something, right? by the way, also having tons if pelvic pain.
