Health Anxiety. Is it possible to create physical symptoms that only existed in your head at first?

Hi all, I’m a 28 year old female and I suffer from awful health anxiety due to different traumas I’ve been through. Is it possible for anxious health thoughts to trigger the physical symptoms you were anxious about which worsen the more anxious you get? Have you ever experienced this? I’ve convinced myself my period pains are cancer or something else. It’s been crippling me this week. Thank you so much.
