Holycow! Vibrating i have never heard of this,,,i guess may be you are concerned about detecting ovulation! Are you ttc?
i say this because, when trying to conceive even i wish to detect what is going on, with this knowledge on ovulation and implantation and pregnancy symptoms, i concentrate on my reproductive things and i fell the same,,,
Try to concentrate on some other thing and check after 2 days,,,if that persist please consult a RE,,
Get well soon:)
