9 weeks and no true symptoms

My wife is 9 weeks pregnant with our second child. She is noticing sore breasts and overall fatigue. No real ligament pulling or stretching like the first time around. Is this normal? She had a sono done at 5 weeks and our child looked good with no concerns and a early HR of 101 bpm. They said its low but since she was so early they were not concerned. She's worried about going in 3 weeks and they see baby is either not growing or deceased since her symptoms arnt progressing. She is also on vaginal progesterone since we miscarried last year. Advice or thoughts?
