Thank you for your question.
We recommend letting your doctor know that ongoing staining is a difficulty for you, even when it is not medically a problem. Your doctor may have suggestions for how to limit the staining.
In order to start the seven clean days, we recommend trying to clean out the vaginal canal gently and thoroughly, and then waiting a little before performing the hefsek tahara. You may skip the moch dachuk. It is important to do one bedikah on the first day and one on the seventh day of the seven clean days, as well as one during the intermediate days. If you feel it is necessary, you can skip other bedikot. If the spotting continues, you can use a disposable pantiliner during the clean days and disregard small stains found there. It is important to note that not all shades of brown& render a bedikah invalid. If you are unsure about a bedikah, we recommend consulting a halachic authority. We hope this will help you get to the mikveh sooner.
For precautions you can take to avoid becoming niddah from staining, please see our guidelines here.
We hope the hormonal patch will help you successfully manage the symptoms of menopause. Please write back with any further questions.
