Hi, Welcome to HCM, I am Dr. Das
First of today is your 25th day day of menstrual cycle assuming that you have a 28 day cycle and no irregularity. Now, you have no choice except to weight for 15th September. Because, once ovum is formed either it will be fertilized or will die. It takes place around 14th day of a cycle. So, once you passed that period, if the ovum is not fertilized with sperm, nothing can cause pregnancy
. So, wait and see the result.
