I've been having this sudden, really sharp pain in my vagina that only lasts a few seconds, but it's happening at least once a day now. On top of that, I'm experiencing pain on the right side of my abdomen. My periods have been all over the place too; sometimes they skip a couple of months, and other times they're on time. It's kind of worrying, and I'm curious to know what's causing this stabbing painit's so intense it leaves me speechless for a moment. Is it like muscle contractions or something?
