You need not immerse on your
mikveh night if you are away from your husband. You may delay immersion until it is convenient for you. We recommend immersing the night before you return so you may have contact with your husband immediately upon arrival, but ultimately you may immerse when it best suits you, even if it is the night following your return home.
After you complete the
seven clean days you may switch into colored underwear and need not perform any further
bedikot until you immerse.
Please feel free to get back to us with any further questions.
