Anxiety during TWW

We are TTC for #2, but have been pregnant twice (1 MC). We were very intentional each time, so I know my body enough now to know when I ovulate and how to get pregnant quickly. One thing I know is that I cannot get pregnant when I’m stressed. So this cycle, I was very intentional about reducing my stress. I have been working out, eating great- all things I was doing when I got pregnant the first 2 times. Well, yesterday I had a peppermint mocha, which had caffeine in it (I don’t drink caffeine). A couple hours later, it started making my heart race like I had anxiety. Knowing that anxiety and stress is not good while TTC, I started getting even more anxiety. I had a horrible night and didn’t sleep. I still feel that anxiety in my chest this morning...

I am 5DPO and looking for hope. Has anyone experienced anxiety during the TWW and still conceived? I am very blessed to already have a child- I know this. But we are ready for some hope after tragedy. I am terrified that my anxiety has hindered my chance for conception. Can you please share related experiences? Thank you!
