Can she be pregnant or is she just being paranoid?

Hello, my girlfriend and I recently had oral sex and she is freaking out. When i ejaculated, some of the semen got on her hand but she wiped it off with a few tissues and about 5 minutes later or so she went to go pee and wiped her vagina with a tissue. Another 5 minutes later she went to shower and washed her vagina. At first she was worried that she could get pregnant since she did not thoroughly wash her hands with soap and just used a tissue. Today, she says one of her boobs are more squishy then the other. Not sore or anything she just noticed it was more squishy. I know this is an early sign of pregnancy but i told her to stop worrying about it because if she keeps thinking about it her body will trick her into thinking she is pregnant and it will give her the symptoms. I just wanted to get some help from someone and confirm it or if i actually have something to worry about. She is not on any birth pills and she is a virgin. Thanks in advance

Well, key bits were naked.  Condoms were invented for a reason.  Take care.

It does not sound like there is any chance she is pregnant.  That said, being naked and doing things involving ejaculation without protection is a terrible idea; perhaps she is worried not because she is "paranoid" but because she knows your behavior was risky.  Her period will come in due course, unless she is so stressed that her emotional state makes it late.  Please be supportive and not critical, suggest she try to relax, and have her take a pregnancy test (for her own peace of mind) two weeks after the unprotected sex.  And stop trying to be more clever than biology.  Get her some protection and for heaven's sake (and your own sake), you wear a condom.  Unless you are just dying to be a daddy.
