Paranoia about sex following a contraceptive failure

So in April, my OH and I had sex and when he pulled out, he noticed the condom was broken. When discussing, we were positive that it had broken during sex and therefore he had ejaculated inside me. Of course, I had a consultation with a pharmacist and I took an emergency contraceptive pill a few hours after the incident. I have literally just finished my period - the pill delayed it by a week which is normal - but now, I'm getting to the point where my body is seeking to want to get intimate with my OH again but I'm as paranoid as shit about having sex again because of the failure last time. I've got new unopened condoms now which I will use instead of the ones we were using. I'm going to discard the other ones because I think that's not helping my paranoia. Has anyone got any advice on how to overcome the paranoia? I don't particularly want to go back into hormonal contraception because of the effects it had on me mentally. Any advice greatly appreciated.
