Wtf am i or not

Okay so im 29 days late . i went to the doctor today. (Mind you it was not my fmu i had peed like 5 times b4 i went but she still insisted on a urine test only) so she said it came back negative. Then proceedes to tell me "you really need to lose some weight since you arent pregnant" im like bitch. Yea I'm fat i know but why tf hasn't my period started since literally June 27th and it's now august 27th. She literally didnt address it at all. I took a hpt when I was like 3 dayz late and it was faint positive. Idk what to do im so confused.
