###Human: Does stress affect my menstrual bleeding? ###Assistant: Hello. Be relaxed. Once you have your periods, it is enough evidence that there is no pregnancy. Yes, the mind controls the periods' dates, amount of bleeding and ovulation too. With so much stress, your period will show changes. I am 100% sure that there is no pregnancy. I was sure in the beginning itself. If u still want a proof, you can have a serum beta hCG blood test. This will diagnose the smallest of pregnancy anywhere in the body. I would suggest to relax and forget everything. You are fine. Hope I have clarified your query. For more information consult an obstetrician and gynaecologist online -->
