If you are concerned the two step process is generally: 1) do a pregnancy test 2) contact your ob/gyn (doctor who handles your pap smears) If the grinding was completely dry, and no semen was involved before fingering took place, your risk of pregnancy is low. Stress, etc. can slow a period cycle, but it would still be best to talk to your ob/gyn.
