Menstrual cycles can be baffling, and that's why we have a poster explaining this special time of the month. Be amazed as the estrogen takes a nosedive right before ovulation! Check out the egg as it takes its long journey through your reproductive system! Marvel at the luteal lunacy! It is all so very exciting and just what you needed for your bathroom wall. This 18" x 24" poster was printed in the USA.
If you need more menstrual gifts, The Good Ol' Menstrual Cycle is also available as a shower curtain, blanket, beach towel and other cool gear in our Threadless shop!
