getting a sharp pain then I feel like I am going to be sick

Hi,
Welcome to ehealthforum,
It is difficult to comment on the cause for the intermittent abdominal cramps that you describe without examining you. If your symptoms have been persistent and not resolved within 3-5 days, you should consider visiting your doctor/gynecologist at the earliest for further evaluation and assistance. The exact cause can only be made out after careful evaluation. Consider visiting your doctor/gynecologist at the earliest for thorough examination and further evaluation to look for the underlying causes like PID, endometriosis, gastritis, etc. Treatment as indicated (based on examination findings and investigations results) would be started to help you control the symptoms. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle.
Take care.
