###Human: Other than pregnancy kit, what can I opt to check pregnancy? ###Assistant: Hello. I can understand your concern. Irregular periods can occur due to many causes like stress and strain, dietary changes, etc., leading to hormonal imbalance. General conditions like anemia, thyroid abnormalities, etc., can also cause irregular periods. To find out the exact cause of the problem, please go for a blood test to check pregnancy which is more accurate than a urine test. If that gives negative result, pregnancy is almost ruled out. The other option is ultrasound, which helps in ruling out the pregnancy and also to find out other possible causes of irregular periods like PCOD, etc. Hope I have answered your query.
