ADVICE PLEASE!!! HEAR ME OUT!!!!

me and my s.o. are TTC and first day of my last period was Sept. 5th, on my ovulation calculator it had said that I would ovulate somewhere between the 14th and the 19th and my due date was to be June 12th,18. during that two week wait my anxious self buys 2 Family Dollar First Response tests (took one a day)... both came back FAINT POSITIVES. I go to Walmart and grab 3 Ept Tests (took one a day) and TWO out of THREE came back FAINT POSITIVES. I then go back to family dollar grab TWO more, AND from the time I've ovulated I've taken 9 TESTS 7 ARE ALL FAINT POSITIVE LINES!! here's the catch, the app said that I would have implantation on the 19th of Sept. (not so for sure) but my period was to be expected on the 3rd of Oct. on the 5th, I had what it seem to be implantation bleeding,very light to where I knew it wasn't my period, then it turned into like a brown discharge what just stopped this morning. I've had mild cramping(NOTHING LIKE MY PERIODS),very bad nausea at its finest,bad mood swings, lightheaded at its finest, my body gets very hot not like outside hot but inside, I've had a couple sharp little pains, my boobs tingled for a bit then felt as if the was ifting but a burning feeling, I've been with my S.O. for 7 months, NEVER ONCE did I see him throw up our the blue TWICE back to back. my friend that lived with me said she knows someone is pregnant but don't know who.. my sister is pregnant also but my friend and sister don't hang around, my friend also said that one morning she felt very sick like she has to throw up and gags when she walks into my room... I'm honestly CLUELESS,because I feel as if I'm getting mixed signal! SOMEONE PLEASE ENLIGHTEN ME ON SOMETHING.I KNOW ITS LONG TO READ BUT HELP PLEASE!
