Help!!

I had multiple sessions of unprotected sex daily from the 22 to the 25 of November. On the 22 I was, according to glow, 2 dpo. However, now Ive been nauseous everyday, my lower back has been killing me, my breasts are super sore, and they grew a tiny bit. today I got sick from the smell of orange juice and I love orange juice. on December 1st I had this vvv light pink spotting just once when I wiped.(tmi I’m sorry) and yesterday I had a very mild cramp. These aren’t my usual PMS symptoms and I’m expecting my period tomorrow. I took a pregnancy test yesterday evening and it was a negative( I also drank a lot of liquids before I took the test) Could I still be pregnant?
