pregnancy scare?!!!

Need advice! Thanks everyone. About 2 weeks ago I had protected sex but when we were done we realized everything was in the floor, we kinda just ignored it and said it probably just fell out bc the condom had no holes or ripes, me and my bf have continued to have sex but today while I was eating I felt The urge to throw up while eating a grilled chicken sandwich, it was horrible and I was no longer able to eat! Could it just be me or could it be a symptom of pregnancy or is it to early to tell? 😞
