Patient's question:
I should have gotten my period on the 4th, but it hasn't arrived yet. I've been taking pregnancy tests every day recently, and none of them have shown pregnancy. My period isn't coming, and I'm very worried. Am I pregnant? Is the accuracy rate high with pregnancy test strips? What detection method is best to use? Can an ultrasound be done?Doctor's answer:
Generally, if you miss the deadline by three days, you can use morning urine to determine if you are pregnant. If it's been more than a week, even without morning urine, you should be able to detect pregnancy. I believe you are not pregnant, and it may be due to other reasons causing irregular periods. It's important to note that emergency contraception can disrupt the endocrine system, and your delayed period is likely due to this reason.
