Not sure what to think…

So yesterday my period was due I took a FR test with fmu and got a positive 2 hrs later I used CB and got a positive but not pregnant on the digital. 4hrs later I went to my drs office their urine pregnancy test was also negative so I had blood work done my hcg is only at 22! Would that be a chemical? Or too soon? Repeat test on Wednesday 🤞🏼🤞🏼
