We had consumption with condom, but he put it on the wrong way, so he flipped it after some time

I had sex exactly one week ago and I'm almost positive I was ovulating. We used a condom and we are sure it did not break. However, we began to put it on the wrong way and flipped it over once we realized. I'm worried that preejaculate could have gotten onto the side of the condom that was in me. I feel like I'm having possible symptoms of being pregnant, I've been feeling them for about 3-4 days now. I've noticed that I've been getting brief headaches on one side of my head (sometimes the right, sometimes the left), aversions to food, somewhat tender and larger breasts and the veins seem to be more prominent, slight nausea on and off, mood swings, slight cramping and twinging in my uterus and it feels harder to me, yesterday i noticed very light bleeding when I went to the bathroom, today my vagina seems swollen, and I noticed a little bit blood when blowing my nose earlier also. I'm not due for my period for about another week and a half. I just need some second opinions here. I know it's too early to test now, but I plan to test this weekend and then next weekend if it is negative. Could I just psychologically be doing this to myself because I'm paranoid?? Any input would be very much appreciated, thank you!
