Need advice please

So idk if it's too soon for this to happen but I just had sex 3 days ago and we did use protection but today I noticed a creamy white with light pink discharge.. I have been pregnant once but I don't remember this happening before.. this isn't normal for me and I'm not sure if the condom broke but would it be too early for this to happen...how can I tell if it's just normal or if I should be worried?
