Nausea

Today I’ve been feeling really nauseous. I’m 11dpo, took a cheap pregnancy test (Pregmate strip) and it came out negative.

If I was pregnant, shouldn’t the PT be positive since apparently I have enough HCG to make me feel nauseous? Can I be nauseous and get a negative PT or am I out for the month?

I mean obviously people get nauseous for many reasons but I just wanna know where this stands in regards to pregnancy. Thank you!
