Help?!

During my last period my boyfriend and I had unprotected sex, every time since has been protected. My period was due to come on jan 27th but when it was a couple days late I didn’t worry because it comes late sometimes. But this time around it was later than usual so I panicked and bought a test. Today (feb 2) my period still hasn’t come, I took the test and I see the faintest line, so faint that the phone camera won’t even pick it up. I plan on buying another test later today but I’m just curious what you guys think? Edit: every symptom I’m having is both period and pregnancy symptoms. (Cramps, headaches, exhaustion.)

Edit 2: I took another one and it came back negative, still no period, just confusion haha
