Sac measuring small

Had a subchronic hematoma with bleeding and clotting two weeks ago which shows it has reabsorbed on today’s ultra sound. Baby has grown but sac is measuring a week smaller and dr wants me to come back in 2 weeks to remeasure. Feeling bummed ☹️ we were going to tell MIL today but now decided not too until we know more. 7 w 4days hb was 134
