Low lying placenta?!

Lucero • Mommy of 2.♡
I'm 14 weeks pregnant with baby#2 it's a boy 👶🏼💙 super happy anyways i went to the ER a few days ago due to bleeding and he said its just shedding of the vaginal wall that some women don't get rid of that in the first part of pregnancy or not at all and I did diring my second trimester and so it freaked me out because it was red cherry red and the next day it turned dark red and than brown now I'm not even spotting thank goodness 🙏🏼 but we did an ultrasound at 13+5 finding out I have a low lying placenta that if it doesn't go up by week 20 or so that I might end up getting a c-section! I DONT want that have any of you mommies ever experienced a low lying placenta? And ended up in a vaginal birth? And advise on sex? We're you able to have sex normally or not at all ?
