How early is two early to know if pregnancy and for test to come back positive.

Amber • Was ttc for over 10 years. Infertility on my husband end that we were able to fix. I did a lot of tests and things too.Now pregnant with my 3rd child.

How early is to early to know if pregnant and for test to come back positive? So I think I am pregnant and I took a test last Tuesday and today and both came back negative. I am confused bc I missed my period yesterday and it's always on time at least for a long time now it has been and I never spot before and I was really like spotting last Tuesday and yesterday like super light called doctor and they said probably nothing. If I was pregnant would be between 2-3 weeks now so is that too soon to should up on cheap test. I do feel some symptoms too.

Some background on me is we are 10 years ttc went to fertility doctor 2 years ago and found out husband had no sperm coming out so since then he had lots of Apts and 2 surgeries and finally fixed him July 18 I believe it was so we can have kids.
