I agree with Cheryl. Stop trying, that is exactly what I did and within just a few months it happened.
For the pain, I would take Motrin or Advil every 6 hrs (600mg) and it should help. I am sure most of your symptoms are because of the painful cramps you have.
There are miscarraiges you can have early on but, there really isn't anything that can be done. If you were futher along the doctor may suggest a D & C. If your really concerned, make an appointment and see if the doctor thinks you should have bloodwork or any testing done. You know your body best and if this is pretty abnormal to have such a strong intense period do it for piece of mind.
Good luck and I hope you feel better.
