Keeping sex interesting?!

Help! This is only the first month my husband and I are TTC. We had sex more often this month because of that-but most of the sessions felt so boring because we were doing it more than normal. We've been together 8 years and had a lot of sex in the beginning of our relationship but now it has dwindled down a ton. Before TTC we would only have sex 1-2 times a month. Which wasn't a concern for us, we were still extremely happy together. So I guess I'm just curious how you ladies keep sex from getting too boring while TTC?!
