Is this a sign of pregnancy?

I’m a bit stressed!! 😓 I had sex for the first time about a week and a half ago. My glow chart said I was on ovulation on about a 7% risk of pregnancy but I’m on the pill! And we used a Condom and he pulled out. My boobs are so sore and so heavy and swollen.. usually I have very small boobs but they seem so big now!!! My period isn’t for another week and a half either quite worried I could be pregnant! Someone help please
