Possibly pregnant help!

Elizabeth

Okay so I came off my birth control at the end of November. I had unprotected sex on dec 24th and he finished inside of me. I have not had a period since before ending my birth control and that was in the middle of November. I have had no period my boobs and nipples are very sore this started yesterday and I am having a lot of white creamy discharge. I took a cheapie test on Saturday and it didn’t show anything. But is there a possibility of pregnancy
