The last time I had unprotected sex was November 26 & my cycle usually last 30 days and my period is now 6-7 days late but i started spotting 2 days ago. I took a pregnancy test as well 2 days ago and it came back negative. I’m super nauseous today and i’m starting to panic! is there a way i could be pregnant? my period is never this light and late.
