When it's it the right time?

Jessica • Im 28 yrs old and we are trying to conceive. Hoping to have a family soon!💏💋🚼🚼🚼
My period was on the first of the month. And I was wondering when is the right time to have sex. Cause sometimes I feel the trackers aren't helping. So I've heard three days before and three days after... Then a week so I'm confused.
