Pregnancy symptoms

I had sex around May 22-24 unprotected and he didn't cum inside me but we went a few rounds without taking a break and now I'm having a bunch of weird symptoms. I had a really light period 2 weeks after(which I heard some women can do). I have weight gain, my stomach is a little harder than usual, my boobs are SO sore all the time, I'm peeing every 5 seconds, I have the weirdest cravings especially for things I don't usually like, I have crazy dreams, hot flashes, I get light headed really easy and more often even though I eat and drink plenty, and I am extremely emotional and hormonal. I only took one test and it came back negative but a friend told me it could've been a bad test. Am I just crazy? Please no rude comments.
