If you are having that much pain in pregnancy you must go to the hospital. Why are you suffering and on the internet telling us. We cannot diagnose what is going on with you

Talk to your OBGYN about this pain. Is there any bleeding accompanying this pain? Sometimes there is a bit of discomfort associated with early pregnancy, it's your body adjusting to a growing being inside of you. But there shouldn't be pain. If there is, it's always best to discuss this with your OBGYN.
