Thank you for reaching out to us.

Mikveh immersion: In your situation, where you can remove and replace your pessary by yourself without much difficulty, you should remove it prior to mikveh immersion. (If removing a pessary would cause difficulty, it would not be a chatzitzah.)

Seven clean days: Please check in with your physician as to how long it is advisable to keep the pessary out. Not wearing the pessary for the entire week of the seven clean days avoids any interference with bedikot. But if it poses a medical difficulty, you can reduce the number of bedikot to the hefsek taharah, a bedikah on day one of the clean days, a bedikah on an intermediate day, and a bedikah on day seven. You would remove the pessary before the hefsek taharah and replace it after the day one bedikah. You would remove it again before the day seven bedikah, and replace it after you have had relations. You can leave it in for the intermediate-day bedikah, doing a more shallow bedikah.

Moch dachuk: If it seems to cause irritation, or if you often find bleeding on the moch after a valid hefsek, the moch should be omitted.

Because a pessary is inserted internally, any blood found on it could potentially make you niddah or interrupt the clean days. Therefore, to avoid questions, we recommend removing the pessary without looking or in dim light, and rinsing it off before looking at it. This is permissible even during the clean days. If you do find blood on the pessary, you should ask a halachic question, since it may be possible to attribute it to irritation.

Please don't hesitate to write back with any further questions.
