Generally you will ovulate about 12-16 days before your next period is due. Not everyone follows this average however, with some women naturally ovulating a bit sooner, some a bit later.

It will give you a starting place. Increase the odds by trying several days before through a few days after.

Look into some of the ways to try and help determine when you might be most likely to ovulate... predictor kits, temping/charting, watching for changes in cervical mucus.

Remember too that timing is only part of it, and it can naturally take a fair amount of time to become pregnant even when actively trying.
