Best time to avoid BD if trying to wait to conceive?

Not BDing during your fertile window is obvious, but should we not like the day before and the day after the window opens and closes? I’ve already experienced one loss and am terrified of an “accident” with protection. When am I safe to BD without running a high risk until we are ready? We hope to start trying to conceive hopefully by the end of the year. Thank you for any input, it’s appreciated my Glow friends ❤️
