Reason for Concern??

Okay folks,

I need help deciding whether or not I need to see a doctor.

I have had mostly regular periods but sometimes I am weeks late. There have been times where I've gone a month or two without one. I don't get too concerned when I'm late because I know it happens. A couple of cycles ago I was late and I had a really bad pain in my right ovary that felt like I was being stabbed all of a sudden. I was close to asking my aunt to come over to take me to the hospital. Within 45-60min the pain had gone away and I just felt kinda sore. My period eventually came and that was that.

Today I am a week late (not surprising because we just learned that my dad has an autoimmune disease and I've been stressed). I was just sitting on the couch not doing anything when I again got a sudden sharp pain in my right ovary. I could have sworn that my ovary had ruptured I was in so much pain. I couldn't walk, I could barely talk or breathe because it hurt so bad. After about an hour of pain it started to go away. That was about 7 hours ago and I am still experiencing off and on sharp pains.

I am scared to go to the doctor because they always tell me that it's my anxiety or my stress causing whatever I go on about.

Please help me!! Should I go to the doctor in the morning or tough it out?
