New here!

Ashley • Expecting twins May 2016!
Been on here for about a month reading but not posting. Trying to learn the acronyms and all still. ;)
​About me:
​- married to most amazing guy in the world. He's active duty military and we live on a rock in the pacific...which I love. We are moving back to the states in about 2 months. 
​-27 years old. No living children.
​- Last pregnancy at age 24 with my ex ended with a terrible diagnosis of limb body wall and I had to terminate at 23 weeks. 
​- Was on Implanon bc for 3 years and had it removed in January. Went on Nuva ring for 3 months, last one April 25-May 15. Started (not tracking anything) TTC in May. AF May 17-22. Next AF June 18-19 only. Very light and some dark spotting on the am of 20th. BFN on test. 
​So that's me so far! Couple questions:
​1. What is a cycle buddy exactly? I'm assuming its someone who's AF is due around the same time? How do I get in a group?
​2. This has probably been asked a million times but seriously - how the heck do y'all check your cervix?! I have no idea what I'm supposed to be feeling for! 
​I'll try to start being somewhat active here - good luck everyone!
