Bleach Smelling Discharge

I just went to the toilet and when I pulled my knickers down I had a bit of discharge and it smelled like bleach. When I’ve searched online (which I shouldn’t but can’t help myself😫) it’s going on about being pregnant?! I’m due on in four days. Has anyone ever experience this smell, and if so what did you do or what was it?

I’m not planning on getting pregnant, I’m only 18 and I’m not ready at all for that kind of responsibility. Any help is appreciated, thank you😭💓
