Crazy day !!

So had a scheduled ultrasound with the hi risk doc today.. Everything is good with the babies but doc thinks I have a sub chronic hematoma which could make my placenta detach if I'm not careful, they wanted me admitted asap so after a lengthy discussion with my husband we decided it was best so I'm here for two days at least.. Already ready to go home though.. The doc told me that both babies are exactly 1lb 11ounces and that is a little below the growth curve but for me it's normal bcuz all of my previous children have all been small when born I.e 5 pounds all the way to 3lbs 14 ounces.. Has anyone else been told this about the babies being a little smaller and still have everything turn out okay?
