I began what ended up being a 7 week course of accutane on December 28, 2011. For the first four weeks I took 20 mg then switched to 40 mg for the last three weeks, but probably only took the pills about 2/3 of the time because of severe side effects. I ended my course on February 15. I had unprotected sex with my boyfriend yesterday and am very scared that we may have conceived. What are the chances that the fetus would be deformed or hurt in anyway if I end up being pregnant?
