Stage fright/Need advice

Samantha
Hi my name is Samantha and I am new to this. I live in VA and my husband (who I have been with for 10 years) and I are TTC our first. I'm nervous because, I'm so excited, and I'm afraid I'm going to sabotage my own body. Everyone says don't try too hard, it will happen. My fertility window starts tomorrow. I'm not up to speed on all of the lingo so you will have to bare with me if I am getting something wrong. What do you do to "not think about it". I have been waiting for so long for this to finally start happening. We've been married for 3 years and I think I have been harassing my husband (slightly) since our honeymoon. But now I feel like I have stage fright. How do I stay calm?
