im scared

so I am pregnant 12w 6d and have an anterior placenta... well me being told this twice now was like Wat r the risks of an anterior placenta... so I get told generally it's not a big risk for most pregnancies but due to having a c section I'm at a risk of having placenta accreta... me not knowing what that was looked it up on Google and got freaked out cuz it said the risks basically get broke down into 3 things that could happen...

1. I would be at higher chance of miscarriage.

2. if I carry and deliver fine could bleed out.

and

3. I would have to have a hysterectomy.

I'm so scared there is however a chance for the placenta to move up still... I have to wait until 20w and see if it is embedded into my scar tissue from my first pregnancy I'm so scared and don't know what to do or think can anyone help??
