Your best bet is to apply a silicone based cream or gel available over the counter. That is the only cream/gel shown to actually work ( Not Mederma which is sold next to them).Wait till three months after your delivery to have the scar re-examined for possible revision.Good luck and congrats!
Scar therapy during pregnancy
I would recommend massage therapy and application of Plato's Scar Serum on the scars.
