Pains & Bitter Taste- HELP PLEASE GIRL TO GIRL

I had unprotected sex without withdrawal on the 2nd day of my ovulation cycle and unprotected sex with withdrawal on my highest chance of pregnancy night (which for some reason glow didn't say was my ovulation day?) and tonight (final day). I have been having pelvic pain in my lower left side to the point where it hurts to have sex at times. Im also peeing constantly (over 20 times just today) and my discharge tastes sour (but doesn't smell). I just got all of my test results in and I'm healthy! I know it would be too soon to tell if I were pregnant but could the discharge and stuff be a very early sign? I've read that it can be but only from unreliable sources...
