When having my first at 4 weeks Hcg levels were still very low, (undetectable on some test, had to get 2 blood tests to make sure was rising) can this happen again. TTC NO.2 ovulated according to apps around 4-8/ 11/16. 5 days till AF due and faintest line ever on tests. (Probably looking into it too much). Had low cramping since 10/11/16 daily on and off through the day and mild in pain. In last 2 days felt very nauseas but could this be my brain tricking me?

Please can people comment with there own story's? Would love to here if people got negative tests then positive within days? Just don't feel normal something inside me saying I don't think it should be negative....

Thanks x x
