Need reassurance

Hey girls just wondering if anyone can put my mind at ease, I’m 4 weeks 4 days atm got a positive test at 8 dpo all tests getting darker and took a weeks test yesterday showing I’m 2-3 which is 4-5 weeks all tests seem perfect but I’m worried cause I’ve had two miscarriages in 2020 and i was having some cramps last week for about 2-3 days then it just stopped ive had no bleeding and have tender breast increased hunger I need to pee a lot and have some back pain with a slight bit of sickness that comes and goes, is my pregnancy progressing okay is it normal to have that cramping a few days before aunt flow was due and then disappear? Have early scan in September for 8 weeks
