Is it to early to test for pregnancy

According to the app I’m 3 weeks and 1 day , can you test at this point??

Should I wait to miss my period ?

Should I test now ?

I’m so nervous after getting af last cycle .

I’m super nervous .

Me and my partner have been working really hard this cycle . We used preseed , prenatal tables and we prayed .

He is so excited for the bfp but I really don’t want to disappoint him 😭

I miscarried a few months back and it’s really affected me .

What should I do ??
