Yes: Repeat the plan b; then see your doctor to get on a more reliable long term birth control. There are lots of options. Nexplanon, nuvaring, and Mirena (levonorgestrel) are especially convenient.

Thanks for asking!: No, the best things you can do is being getting check by your doctor, obtain a blood pregnancy test to check the levels and if appropriate to get a tv sonogram done.
