Desperate, I need advice...

So I'm 35 since June I have twins, and a 9 year old. I desperately want another with my DH. In July my ob did some blood since it's taking a long time TTC. she said that was normal. I go back in 2 weeks. My dh doesn't have insurance, so we're thinking of buying at home test kit for him. And I almost baught clomid online, but didn't cause Dr supposed to monitor your process? Advice please, no rude comments it's hard enough. I'm willing to try almost anything safe...
