Yes, you can start using Oekolp Forte regardless of the day of the cycle, e.g. during or immediately after ovulation.
According to the manufacturer: "In women taking continuous sequential HRT, OEKOLP forte may be started one week after the end of the cycle."

"In the case of atrophic changes of the lower urogenital tract: 1 globule daily for the first weeks (maximum 4 weeks), followed by a dose of decreases as symptoms subside until a maintenance dose is reached (e.g. 1 globule twice a week.)"

The dosage method depends on the condition, so you should strictly follow your doctor's instructions.
