I only went to the Drs with my first 2. With DS#1 he was happy with the HPT results & did nothing further. With DS#2 I had bloods done as I wasn't sure how far i was & wanted to be sure. But they didn't ask me to do a urine test first. With this one, I knew I was pg so just booked in to the hospital & had the routine bloods done at 12 weeks.
