Have you gotten pregnant with pre-cum?

My husband and I have been using condoms for the last 5 years. Sometimes we don't use one, for example if my period just ended. We always start without a condom, and whenever he is getting close, he puts one on to finish. My cycles have always been between 30-35 days, but the past couple have been 45ish days. I think my new antidepressant is messing them up. I'm now on day 53. I have no signs of starting soon, but also no signs of being pregnant either. I haven't taken a test. I really don't think I'm pregnant.
