I been using this app now for a couple of months to no when I am convincing, but in December me n my partner decided that I could try convieve plus n now I'm pregnant I conceived around Xmas time so only a few weeks, we found out on Monday 18th my hcg was 103 n on Wednesday 20th my hcg was 360. In 48hours it had tripled not doubled. What does that mean ?? Got my scan on Monday x
