Possibly Pregnant..? I need answers!

Hey everyone,

I am five days late for my period. My period is always on time maybe a day early or late but that’s it. The first day my period was supposed to be (Monday) I had all the symptoms -sore breast, cramps, headache, slight nausea, sleepy, period poops; but no blood! I did notice yesterday thick white discharge as well. It’s the strangest thing and I never had it happen before. I have been getting random times where I just want to throw up even getting the extra saliva and sour taste. My boyfriend and I do not use condoms and we use the pull out method (no BC). Idk what else to think other than pregnancy 🥴. Please let me know if anyone else had experienced this before or what you think.

P.S - I just took a pregnancy test but it says negative and not sure if it was too early to take. Also, I am 25 years young.
