Actually ttc but I feel paranoid 😫

So last month I actually took ovulation tests and tried preseed but then the two week waiting period was stressing me out. I workout about 4 times a week by running and biking so I kept thinking what if that kept implantation from happening and what if my husband and I didn’t have sex right when we had to. Well I took a break this month but I really want to start trying and keep it going. So I’d like any advice or if you’ve been through this. Did you stop exercising? 🤔 not even sure if I should just go with the flow. 😩 I trust Gods timing but I also want to put a bit of our part in any way we can. We’ve been married for two years and a half no birth control but again not really kept up w my ovulation days so I guess I been going with the flow for a while now.
