Tiffany, go to your regular doctor and your OB, and do it in the next week. You could have an ectopic pregnancy (the fertalized egg lodges in your fallopian tubes) and if that's the case you need to do something quickly. If it's not that then it may be something else yucky. That kind of pain is generally a good indicator of something important. If you can't get a quick appointment try to get one of them on the phone, or at least a nurse, and tell them what's going on. Good luck! I'll be praying for you!
