Hello there. I can understand your concern. After about one week of your missed periods you can undertake a urine pregnancy test. There are many kits available in the market like preganews, i can, velocit, etc. You can use any. They all work on the same principle. And yes they are pretty accurate. Also you can get a ultrasound and that will also be helpful. Kindly consult a gynecologist for further management. Best regards. Dr. Anil kumar jain.
