I'm getting so frustrated🤬

I'm 7 days late I haven't had sex since 5/8.. all my pregnancy test are negative.. I'm not stressing, exercising excessively, or had dramatic weight gain.. my menstrual is typically 26 days never longer & here I am on day 31.. I've been ttc for 5 months now.. last month I was down about the negative test so I stopped trying & sex became natural. my partner and I have had a falling out since then so we are not any longer sexual.. he was a good friend of mine & we still talk.. so I must emphasize that I am not stressing over it.. my nipples have been tender since 3 days before my expected period, I have very mild nausea, mild headaches every morning besides yesterday, with this annoying sensation on the right in my pelvic area as well as frequent urination.. can I be testing to early? I've taken one every day since my missed period & the negatives are starting to beat me down.. I went to my ob April 9th & every thing was good to go.. idk what's going on.. please someone I need hope😔 has anyone gone this long and still gotten negative results that turned out positive at an later date? I so want this to be my first👶..
