Am I Pregnant ?

Two at home pregnancy test show as not pregnant, I’m 12 days late for my period. Normally liked clockwork.

Symptoms that make us skeptical of the pregnancy tests:

1) Nausea

2) Light Headed

3) Constipated

4) Sore/ Tender Feet

This intuition makes me think so, but I don’t know? Obviously this would be my first. Thank you for any advice...
