Very low income suddenly

Is it just me or is the income from raven mining just incredibly difficult now? I know i don't have a lot of power, i mine at 24-25mh/s but i was getting roughly 20 RVN per 24h now i can't even get 1 RVN in the span of 24h.. What happened?? My hashrate hasn't changed at all its just suddenly so bad it isn't even worth mining now.
