Severe sharp pain in vaginal area like contractions went away after 15 minutes then pink spotting and brown blood only when i wipe. could it b period?

Prob irreg period: Sounds like an irregular period. Brown usually means old blood that has been sitting at the back of the vagina. If this is not typical for you then track your cycles for the next few months to see if they normalize. Often things get back to normal the next cycle. If you think you might be pregnant check then check a home pregnancy test. They are cheap, reliable and available at any pharmacy.
