How can I get rid of stretch marks because of pregnancy?

Not likely. Unfortunately, even if you did see a doctor, there's very little that can be done to get rid of stretch marks. Some methods of treatment include wearing sun screen lotion (because stretch marks tans differently and a tan will make them more noticable). Also, avoiding any further weight gain. Finally, avoid all the "magic remedies" they sell such as cocoa butter, as they do not work.
