I had sex a week after ovulating, can i be pregnant? i ovulated on the 8th and had sex on the 29

Not likely: How do you know when you ovulated? If you used a reliable method, like ovulation predictor kits and it was a week later, it is highly unlikely.

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.
