Steroids!!!!

Me and boyfriend are TTC, however he wants to start a course of steroids and doesn't want to hinder the chance of conceiving by taking roids at the same time.  He asks me all the time if I am pregnant yet because he is so eager to start them.  I feel like he is pressuring me to perform a miricle and be pregnant straight away! It's pissing me off now and do you lot suggest I do?
