The Good Ol' Menstrual Cycle - 18" x 24" Poster

Menstrual cycles are complex, 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. How do periods work, anyway? Once a month your uterus cleans itself out, sending blood through your vagina into the outside world. Menstrual periods arrive around age 9 to 14. This is a big change but it’s a perfectly normal part of growing up. If you want more info on how periods work, read up on our blog! Or get this poster. If you need more period gifts, The Good Ol' Menstrual Cycle is also available as a shower curtain, blanket, beach towel and other cool gear in our Threadless shop!
