1-2 weeks pregnant - Question

Hi so I've done three pregnancy tests in total. Two were the First Response Test which were positive and the other was a Clear Blue digital also positive indicating I'm 1-2 weeks pregnant . I have also done a Blood test which indicated that I only have 29% of the Hgc hormone. This worried me the doctor thinks I'm maybe not pregnant or that its too early. It was suggested I test again. My first question is, is this normal? Second question is today I've been feeling very bloated. Discharging white liquid and very light brown discharge once. Is this normal also? All answers are appreciated xxx(learn more on Glow: https://glowing.com)
