Missed period.

Gabrielle • ♌️
One week late, I did two clear blue pregnancy tests. Both Negative. 
Now 19 days late. Took another pregnancy test. First response and negative. 
Okay so I'm not preganant but where the fuck is my period? I'm bloated, I take my bra off and my breast seem heavier than normal and I just can't...like literally I can't. Anyone have any answrs or even advice!
