Help me please!!

Kathryn • Atticus James & Landon Oliver Leech 💙
I am currently 11 weeks + 6 days pregnant with twins and a few hours ago I wiped and this came out. 
Yes I know some spotting is normal with twins I already had some a few weeks ago and they told me it shouldn't happen again. 
I just want to know what this is and if should be worried about it before I go to the ER again. So please help me.
