How many DPO to take a pregnancy test?

Kenna

Usually my boyfriend is really good on the pull out method but the other day he said he didn’t by accident. It was in the middle at the highest part of ovulation and him and I both know what could happen and neither of us are mad. But I’m worried and nervous. Period is said to start for me in 14 days. When do I take a test or when would I have to take another one if needed? This is all new to me 😰
