Vaginal contraceptive film

My partner and I used VCF on Friday night with the intentions of withdrawal, but he never pulled out. We were both in panic mode and I douched 5 minutes after this happened, but it was a makeshift douche. Water bottle full of warm water. Ladies, I am very fatigued today and I'm starting to worry. Has anyone else used this "BC" method, did you get pregnant? I'm very concerned, please, PLEASE give me some feedback.
