Low lying placenta

Kat • 3 👩🏻👧🏻👧🏻 & 🌈 👧🏻 after ttc for 2 yrs! 🌈👶🏻 #5 otw! (10wk &14wk miscarriage).
Hey ladies. My anatomy scan and fetal screening came back normal. However my placenta is low (not sure if it's previa or not)...Anyone get diagnosed with this late like me? (20weeks) 
Google is evil and has scared the shit out of me. If anyone has any positivity to spread about this, I would greatly appreciate it. 
This little girl is my rainbow and I don't want to lose her. Any advice, Any ways to be proactive or things to avoid would be warmly welcomed.
Thanks March beauties.
