My boyfriend and I had sex on June 10th, and we didn’t use a condom because it was one of those heat of the moment things (stupid, I know.) I am on the pill but I had missed it for the three days prior to the 10th. My boyfriend came faster than he thought and thought he might have gone a bit inside of me before pulling out (again I know, stupid.) I marked the date on my calendar after he told me that just in case anything weird happened. Today June 18, I woke up feeling really nauseous, and I never get nauseous, I have a strong stomach. I didn’t have any change in diet or exercise in the past week. I know it’s only been a week but it freaked me out.

Is this early signs of pregnancy or is this too soon and it’s just random?
