Besides writing letters, there are some pretty interesting calls to action on the now nicknamed "Women Can't Be Trusted Motion" in which MP Woodworth proposes to make fetuses into persons.

Also knitters and textile artists are getting to the point creating nifty uteri, vulvas, and other lady parts and sending them to anti-choice MPs. Have a look at the group called "Womb Swarm Parliament" on Facebook. https://www.facebook.com/#!/groups/354104927964655/
I'm getting my craft supplies out now, and I think I feel the need to share something about my last mammogram.
