Can i still be pregnant ? 😩please help

Vania • 24 years old .. happily married to my best friend .... #TTC baby number 1 waiting patiently for 2 positive lines ..
I was 12 days late and on the 13th and 14th day i started to bleed i think it was my period but not sure then the i was just spooting so after 5 days passed w no spooting and till yesterday i started spooting again .... Whats going on 😩.. I am so scared right now i have a doctors appointment on saturday ... Now 2 weeks ago i went to the clinic and my urine test was negative before i went to the clinic i took home pregnancy test and they were all negative as well .... And today i took one and is negative .. I know it might sound stupid but i tried doing the home made pregancy test w ghe clorox and on that one it seems like i might be preganct idk im confuse i hope is a baby not something seriousÂ
