Low lying placenta

Any other mommas find out they had a low lying placenta early in pregnancy and have it correct itself later on? Or did you end up with placenta priveria (after 20weeks). Doctor told me yesterday that my placenta is quite low and to avoid sex for now. I've had a little spotting after having sex so I'm guessing it's from that.

I'm just hoping it corrects itself as I dont want any risks or eventually need a c section 😔
