I haven't personal experience of TTC, it just happened.
If I remember correctly from Life Science lessons the ovum (egg) released at ovulation lives for 2 days after released and sperm which enters during intercourse can survive up to 3 days. This therefore means that fertilisation can occur if intercourse occurs anytime within a 5 day window. Up to 3 days before ovulation and 2 days after.
