help please

Help me out here ladies it's been nearly 7 years since I had my gorgeous little man. I found out I was pregnant just short of 2 weeks ago and according to the calculator I should be about 5 weeks today. Only thing is I can't remember for the life of me what I'm supposed to do next. Do I go to the doctors, do I go straight to the midwife at the hospital I'm confused ha I know there's no scans or anything to be had yet but I know that somehow I need to sort antenatal care!! Help 🙈
