My chances low?

I get really worked out when I have intimacy with my husband. He is sooo patient with me, he literally waits for me, I wait until after my fertile window is over and like a week after that so technically we only have intimacy a week before my period is supposed to start so like 1-3 times a month. On top of that we use condom & he pulls out even before he finishes (sorry TMI) yet I still panic. Idk how to go about it, I already have a therapist, not sure if medication will help me. I’m just afraid he’s going to get tired of me because I know I shouldn’t even be panicking but I can’t help it…
