You should not worry.
This is because placental position changes with advancing gestation.
95% of the low lying placenta migrate upwards with advancing pregnancy
and they are seen to be normally located in the upper segment at term.
The only risk you have now is you might episodes of vaginal bleeding which can be spontaneous or induced by activities like trauma, heavy work, exercise and intercourse.
Your management will depend on the placental position at term (37 weeks).
All you need to do for now is take a few precautions to avoid sudden onset of bleeding due to low position of the placenta.
These include adequate bed rest
, heavy work, exercise and intercourse.
Do not go for any vaginal examination unless your placenta gets situated normally.
