Christian vs fertility drugs... God given, or unnatural?

Briana
I've just found out that I've stopped ovulating. It took 11 months ttc dd who's now nearly three and we've been tying one year for #2. I'm nearly 32. My doctor said if there r no probs w DH sperm count I'll b looking at Clomid/clomifene. But I worry that if god didn't will it, maybe it was for a good reason? And should we force sthing unnatural? I know fertility treatment is quite commonplace these days, but it's a new concept for us to consider and I've always thought we shouldn't mess with gods plan and nature. Comments from other Christians please?
