Pregnant???

Lately I’ve been feeling super tired and my stomachs been hurting and feeling like cramps and I’m never comfortable and ive been crying and irritable... my boobs are swollen and I puked the other day but I took a pregnancy test and it’s told me negative. Every day my symptoms get worse but I’m not supposed to get my period until September 1st so I have no idea if I’m pregnant or not. I really feel like I am though. I feel like it was a false negative because I took it really early. I don’t know what to do or think.
