What do you all think?

So this morning I was laying and bed and realized my boobs were pretty achy (not the nipples, but like from inside if that makes sense). I realized I might be close to my period so I checked they app which I hadn’t really done anything with for a few weeks. It actually said that I’m 14 days late with my period. I’ve also had constipation, some on and off cramping, some headaches, and white sticky discharge that doesn’t really smell at all. My sex drive is also pretty high 👀. I have been stressed and a bit dehydrated so I wonder if it’s just that? I took a generic test this afternoon and it showed negative. Should I try contacting my OBGYN for another test? I feel like 14 days past period would definitely show whether I’m pregnant? What are your thoughts?
