Help me assure myself here, pretty please

Hello besty! Can you help an anxious brain rn?

I had my last menstruation from April 12-16. My bf and I had sex 2 days after my last day (April 18) we used protection at first, BUT changed to raw after (basically unprotected) but he withdrew a few minutes before ejaculation, ensuring that no fluid went inside (but still swimmers can still be possibly found in pre-ejac). I assume that I ovulated on May 1 since I experienced egg white-like, stretchy discharge during that time.

I am quite confident that nothing went it, but still, anxiousness occupies my mind everyday. I am currently experiencing some symptoms of PMS but in a hella long duration, so my mind is getting crazy because it can also be a sign of early pregnancy.

Here are/were my symptoms: — Lower abdominal pain (mild): 3 weeks straight UNTIL NOW, on and off every damn day. I always think that I'm gonna have my period later, but nothing comes out T_T — Lower back pain (mild): A week ago for 5 days straight — Nausea (probably due to stress): 2 weeks ago for a week straight — Clear watery discharge: started 2 weeks ago, 2 weeks straight. Still have slight discharge rn.

I have also tested many times.

• May 2 (home test): Negative
• May 14 (home test, twice): Negative
• May 14 (hospital, urine test): Negative
• May 31 (home test): Negative
• June 1 (home test): Negative
• June 3 (hospital, hcg serum test): Negative

I know that the negatives are sure signs that I am indeed not pregnant. My period cycle is usually irregular and hella broken, my cycle varies from 40-47 days, experienced skipped cycles, sometimes 3 months no period. BUT the abdominal pain and other symptoms that I feel right now are not usual for me, I usually feel abdominal pain 2 days before my period, but rn it's running to 3 weeks which makes me crazy.

Help a friend out here assure herself, share your kind comments and thoughts please. Thanks a lot, besty!
