Blood around gestational sac

I’m 6.0 and there was no heart beat today, but a lot of progress and hope there will be on next week at 7.3. My doctor mentioned bleeding around the gestational sac and said not to freak if I bleed a little bit. But didn’t say he cautious or anything.. I googled and am freaking out. Does this look really bad to anyone? I had a miscarriage right before this pregnancy so I’m so paranoid. any advice would be helpful. The top pic is 5.2 the bottom is 6.0 and when the blood was mentioned.
