Could this be my Rainbow Baby?

So, my hubby and I had our first pregnancy in April unexpectedly. I had been praying for a baby but he wasn't ready. However, we didn't use protection and BAM! Unfortunately I miscarried at 6 weeks, and after trying to pass it naturally for 30 days, had a D&C at the end of June. I'm back in school now and last month we decided to start trying again. He's out of town for work a lot, which makes it difficult. This month we did the BD on a Sunday before he went out of town that afternoon, I ovulated Wednesday, and now I'm 12 DPO
I took a test yesterday that appeared negative so I left it it the bathroom and went on with my day. Before bed however, I glanced at it and saw a faint line. Since I've read that you should read the results within 5 minutes, I took another one with my FMU today and saw a little bit of a darker second line. Could it be???
