Think i'm positive and advice on next steps

I had a few symptoms, i.e. tender breasts, fatigue and mild cramping now and then. So i took the PT (clearblue non digital) today, which is supposedly my 1st day of period and the results showed a faint line to indicate positive. Im not 100% sure yet and will retake a few days later. But if so, i shld be 4 weeks pregnant right (from date of last period)? Just wondering where do i move on from here. Am a #1stimemom and i read here and there that i should start looking out for OBs and most of them will only look at you from 8 weeks onwards? Any recommendations too? I've been taking folic for about 2 weeks now (swisse ultinatal, for preconception and pregnancy). Any other advice from experienced moms?? Thanks so muchhh!!!! #firstbaby #pregnancy #pleasehelp
