<s>[INST] I have a very mild stinging in my lower abdomen, almost like being poked by a needle. I had sex about two weeks ago and i am late by seven days. Im not ruling out pregnancy but would this be normal for menstrual pain? I am 23 and have never suffered from mebstrual cramps. My breasts are also very sensitive. [/INST] Hi ! Good morning. I am Chat Doctor answering your query. If I were your doctor, I would advise you for a serum Chat Doctor test to rule out pregnancy. In case of its persistence and your menstrual period getting more delayed, I would consider an ultrasound of abdomen. In the meantime, if you get your normal periods, then nothing to worry, as then you are sure that it was pre-menstrual pain. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem if it permits. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. Wishing you an early recovery. Chat Doctor. </s>
