I've been on the pill (cyclessa) for 8 months now and it's generally been fine. But now I've noticed that I'm never in the mood anymore. I feel like I'm always coming up with reasons not to have sex. My boyfriend and I now only have sex about once or twice a month. Also, my skin is extremely dried out and I've gained about 5 pounds. I'm on my period now, supposed to start a new pack on Sunday, but I'd like to skip a month. Is this safe?
