Hi, I have early pregnancy symptom. Last time period is on august 30th. On sep month 16th I have severe thigh pain, fever for two days. Chance to conceive?

Take a test. Home pregnancy tests are very accurate. They are the same tests used in a doctors office. They can detect a pregnancy 7-10 days after conception. The best time to take one is when you miss your period. If you doubt the result you can repeat it in 1-2 days. If you were pregnant the hormone level would rise enough for detection.
