When to visit gynae

i did mine at 3weeks and when they ask me why i came early i just told them i want to make sure my baby is doing well and scared of another miscarriage. so yeah, i agree with everyone else. 5 weeks a good time to go. for me,the earlier the better. most moms (pregnant 3months) who i met at my clinic said they go late because they hate going to clinic every now and then.
