Pregnant or not pregnant

My nipples are tender to the touch, my fiancé touched them yesterday and I yelled ouch. He grabbed my ankle and I yelled ouch lol. I have been really gassy for days. I have been sleeping hard and snoring which is unusual for me. So we went out to get pregnancy tests because I couldn’t rest not knowing if I was pregnant or not.!! Well I took two traditional tests and they both were negative. The second test I think there was a faint line. Completely unsure in my case what would you all do? I’m also ovulating according to my calendar and today and tomorrow are the highest chances of pregnancy days for me. I’m frustrated because I want my rainbow baby but I’m getting ready to start a new career in law enforcement.!!
