Yes, I think you'll have to frog back or start over.
Next time use a lifeline, too. If you've never use done.. a lifeline is a thin yarn/string/ribbon/dental floss that you put on a needle and work through the stitches on the needle at a point where there are no mistakes below it. Then keep knitting. As you work with no mistakes you move it up. IF you make a mistake you can frog back to the lifeline w/o losing all your work.
