Pregnancy scare???

My period isn’t due for another 2 weeks and I’m on the pill but I took one 14 hours late like 10 days ago. Had sex with my boyfriend for a bit then he put on a condom and everything was fine until he finished when he pulled out the condom was inside me hanging out. I could just be paranoid but I’ve been getting this really creamy white non odour discharge ever since and there is a lot of it. I’ve had a headache and dizziness all week on top of the flu and coming out in sweats.What could be wrong ??
