Possibly pregnant?

Alannah

It’s been about 9 days since me and my fiancé had unprotected sex, it was 16 days before my period (still 9 days to go) typically when I get my period pain which is usually just lower abdominal pain and sore breasts and it usually starts about 3 days before my period, but rn I am experiencing, fatigue but inability to sleep, nausea all day long, constant but steady headache, frequent urinating and extremely bloated, tender breasts and sore/tingly nipples, I took a test yesterday morning that was negative, should I wait the next couple weeks then test to see if my period does or doesn’t show up? This would be my first if I am and to clarify we have been trying for 8 months (not an accident). Any advice helps!
