The pill

I’ve been in the pill for 2 years now and before I started I use to ovulate a lot of clear stuff but since I’ve been on it it’s never like that anymore it’s usually thick . I took my pill 3 hour late 2 days ago and now I see this clear discharge… does that mean my pill isn’t working or ? Should I be okay ? I usually take it on time just 2 days ago I slept and took it 3 hours late
