Subchorionic bleed?

Twins 💗
So I bled for the second time a couple of days ago. Had an ultrasound and the twins are fine. I'm 10 weeks. The sonogropher saw a small bleed on one of the placentas. It's not too close to the babies. Say it should go away on its own but that was my second bleed in 3 weeks so I presume it hasn't gone away in that time. Anyone offer me any advice on what i need to do to heal this? would be great as doctors did not really give me anything?? Thanks in advance.
