I need advice about Clomid!

So my doctor prescribed Clomid and I'm supposed to have an <a href="https://glowing.com/glow-fertility-program">IUI</a> following me taking the Clomid, BUT my husband's work won't let him off to give a sperm sample this month so we may have to wait a few months before we get to try when he can get a day off. My question is, since I already have the Clomid should I take it anyway this month and try conceiving on our own or wait it out? Of course I would discuss it with my doctor but I just wanted to hear of the success rate of Clomid by itself without an <a href="https://glowing.com/glow-fertility-program">IUI</a>..
