I got false test until I was like 10 weeks or aliitle futher pregnant. I figured my period was just really late like always cause I was told I'd never have kids. I still didn't think I was until my bf made me go to the doctor because he said he knew I was. And he was right I was pregnant with our first baby boy.
False negatives are common if you test too early. Most women get a positive the day of their missed period. HCG levels double every 2-3 days so try again after a few days if you're suspecting you might be pregnant.

It could still be to early wait about month thats what i did
