I have been bleeding lightly and I Should be over 5 weeks pregnant. I know when I ovulated as I used lh tests.  I did some tests.  The Digital say 1-2 should say 2-3 at least and Iv done loads of lined tests have a scan in 3 hours and I'm so scared my hormones aren't high enough and the pregnancy isn't carrying on. What do
