My wife has an Mirena IUD for almost 6 months & is still having problems with staining. When she stains on colored is it necessary to abstain from tashmish? What are the guidelines for this?
On a day when there is a stain the size of 1-2 pennies or more from mid day and on, one should abstain from tashmish for that night.
This is a general guideline and not an exact science, in a case of doubt or extenuating circumstances a Rav should be consulted, as other factors may effect this pask. Such as how close to her period she is, the color of the stain and other considerations.
