Little Advice

My period is about 28 or 29 days late. I had unprotected sex the 22 of October. I’ve been really tired a lot more than usual. I have been very picky of what I would want to eat. i have been having minor cramps and extra sensitive. I also been having like white discharge coming out with no odor though. I took three test and all came back negative. Now my nipples are little sore. Am I pregnant or just overthinking?

No, i haven’t taking a plan B
