Late positive?

Alicia

How late have people received a positive pregnancy test? I had my period November 14-18 but I am usually very heavy with clots and this one was only moderate for a day and light to spotting the other days. At the time I didn’t think too much of it but for around 5 days now I’ve been nauseous most of the day. Last night I was even a bit light headed as well even after I ate dinner. Also been having headaches and tender breasts.

I took a premom brand test this morning just to see and it was negative. If it wasn’t actually a period I would be around 5 weeks 4 days. Anyone not get a positive until later? Like 6 weeks?

Just wondering what might be going on😣
