First time ttc here

Hi, its my cd52 today, 32dpo, my period is late for 14 days already. I’ve checked using pregnancy test kit but still negative. Should i wait for another 2 weeks to make it a month then i should make an appointment to the doctor? What should i do? I have like headaches & cramps on my left side on my period cramps area(on for a short while then off for a few minutes and it repeat again, every single day). Im pretty worried if theres no 2 lines & i keep getting 1 line. 🙁 #adviceplease #Ttc9monthsfirstchild
