7dp2dt and Stressing

I will be testing in 5 Days time and I am starting to stress again, I was so calm and positive the past week and now that anxiety of failure has returned, the 2ww sucks big time and really messes with ones emotions. At the moment I am have strong AF like cramps and lower back pain and it feels like AF is going to start any time soon now, running to the loo every few minutes to check if AF has started. Ai ja what can I do but wait and wait and wait................. I want to stay positive this time around but ja what can I say!
