Is there a safe way to delay ovulation in a normal cyle by just a few days?

Possibly. By taking Clomid (clomiphene) starting on day 5 you can sometimes push the day of ovulation a couple of days later. This is not foolproof. It is more likely to work if you have a very short cycle and ovulate early and are trying to ovulate closer to day 14. There is a 5-10% risk of multiple birth (mostly twins) so it is not without risk.
Not to my knowledge. There are medications that stimulate ovulation and medications that can pevent ovluation over the course of a month or more but I am not aware of any treatments that can delay it for a few days. A gynecologist would be best to answer this question.
