Cramps daily?

Tested negative first 2 weeks of this year. Wasn't expecting much since we did it 5 days before my period about to start. But the period never came and I still got cramps. So yesterday I went to a doctor at polyclinic for the cramps and she made me take another test and now it's positive. I'm kind of worried it might be false or something is wrong. She gave me a referral to Nuh but I think it might take some time before the appointment. Should I wait or go make an appointment myself as private patient at Nuh?
