Sex drive low now that I'm on the pill

Alex
Has anyone else experienced this? I switched from microgestin to Chateal and I've noticed some change. But my SO and I have been together for 3 years and we used to have sex numerous times a week. Now we sometimes don't have sex for a week. I really enjoy when we do, but I never initiate it because I'm never in the mood. And I think my SO is scared to initiate in case I turn him down (which I've never done before). We are both really attracted to each other. Sometimes I also feel really bloated from my birth control, which I think might make me feel icky and not in the mood or sexy. I just don't want to feel alone. Is anyone else experiencing this? Or even better, have you experienced this in the past and have answers for how to fix this.
