Pregnancy test shows up not pregnant and then pregnant every other one?

Different brand pregnancy tests work off different levels so as one brand could say positive another could be negative. This is nothing to worry about it's just one brand doesn't pick up the pregnancy hormone as early as the other brand. This early into the pregnancy it is not essential to be seeing a doctor. I was 10 weeks pregnant when i realised and took the test and made an appointment to see my midwife. Stick to one brand (a good realiable one) and take the test again first thing in the morning. This is when the test is most accurate. Eat well and fingers crossed it's what you hope for x
