lubrication and bc

Hey girls 
I've been on the microgynon 30 pill for about 6 months now and I've noticed that I don't get wet as I used too, which is really annoying cause it makes a massive difference. Spoke to a few friends and their stories were similar, since on the pill they can't get as wet as they used to. Has this ever happened to anyone? 
Does bc reduce lubrication due to the thick mucus to stop pregnancy ? 
How do I stop this? Is there an alternative bc I can take instead? How do we stay wet? Without the lube
