Hello doc can i use clomid on my 3rd day or 5th day cos i start using it on my 3rd day when can i have contact with my boyfriend?

While the 5th day is traditional the 3rd day is fine. There is no restriction on sexual contact. This applies whether you are taking Clomid to try to conceive or if you misspoke and are actually referring to a birth control pill.

It makes no difference whether you start clomid on Day 3 or Day 5 of your cycle. You can start having intercourse on day 11 onward - every other day is equally effective as every day. Also use urine ovulation kits to check for ovulation.
