<s>[INST] My girlfriend s period is delayed by 10 days. She is worried that it may be the result of helping each other in masturbating, but we did in turn and their was little time in between.. Nd we took precautions and wash hands before. She is still virgin. Is there any chance she is pregnant?? Please help [/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. According to your question the possibility of pregnancy is less. Delay in periods can occur due to many causes like weight or dietary changes, stress and strain, hormonal imbalance, general causes like anemia etc. As periods are delayed by 10 days, let her undergo urine pregnancy test once.If test gives negative result, she can consult gynecologist once and take tablets for withdrawal bleeding. If irregularity of periods persists, she needs evaluation with basic investigations like hemoglobin, blood sugar, thyroid profile and ultrasound. With this work up the possible cause of her problem can be identified and treated. Hope I have answered your query. Let me know if I can assist you further. </s>
