Flu or pregnant?

Tyra • My 2 rainbow babies Emari 04/08/17 & my son Drew 08/21/18 & my baby boy Emon 10/15/19👶🏽👶🏽💙💖

These past two weeks I’ve been throwing up in the morning and my breasts hurt so bad and it goes off and on.. I told my doctor I feel like I’m pregnant and had three pregnancy tests have a vvvfl well I did two blood tests and they were really low and she there way no way I could be pregnant but I have not started my period I’m 8 days late and still sore boobs. My throwing up got worse last night I felt like everything was making me so so sick. I couldn’t even hold a water down. I’ve been having body aches.. and a sniffling nose. Still af hasn’t shown her face. So I’m confused am I pregnant or sick? I mean could it be really early that’s why the blood tests were negative? I feel like everyone thinks I’m crazy and it makes me feel like I’m crazy.. I feel like my body knows though. I’ve been through it twice. Any advice ladies?
