Worried its misplaced

McDonald

So one day i checked my strings and i couldn't feel em, now i can but only the beiginning of it coming from my cervix and it feels like the rest of it is wrapped around my cervix. I used to be able to feel the tip of it but anymore. As a result i did try to tug it a little to see if i could feel the tip of the string but i still cannot. Is this cause for concern? Should i abstain from sex until i can see a doctor?
