Separation in womb

Hey ladies!! So I’m measuring 7 weeks and ever since I’ve been pregnant or maybe a few weeks in I’ve been spotting with brown/pink discharge I finally got an ultrasound and the doc says that there is a separation which is the placenta being away from the wall and it seems like its possible I’m having a threatened miscarriage we saw a heartbeat but I’m still worried she told me to take it easy but my stress is at an all high has anyone had this and went on to have a healthy baby?!?
