no symptoms, 5 weeks

I recently just found out I was pregnant, my period is 4 days late & I had a faint, but visible, line on my tests. The only symptom I had was breast pain. It feels like a tingly burning pain down the center of my breasts, towards my nipples (comes and goes but no nipple pain AT ALL, just breast) did anybody else experience this? I haven’t been to the doctor yet, FTM.
