My period is due in five days. I have been having a number of symptoms but all of my symptoms are symptoms that happen with PMS & pregnancy so i just needed some opinions?

My symptoms include:

SUPER sore boobs - This concerns me the most because they hurt so bad and I dont usually get this during pms

Cramping

slight back pain

Increase of appetite

I have no spotting. But my boyfriend and I had sex and he pulled it out but his sperm did land on “me”. but not in me.

Could i be pregnant? (I read that if it lands close the sperm could still swim inside) I’m genius scared & I just need answers

I know I should be using BC..

update: took a test and it was negative :)
