5 days from AF and I'm so nervous

I'm extremely nervous... heartbreak of last cycle is giving me PTSD to test this month. Symptoms this time have been really strange and currently I just have a feeling of discontent but not in a bad way.... Nipples are still tender but not as bad as the past few days. Breasts are still full. Cramps I'm blessed they have hardly been around if at all vs last time. Any advice on remaining calm, how I should be feeling about symptoms????
