last month I had an early misscarriage, 4 weeks 4 days. If I hadn't tested early I wouldn't have known other than my crazy amount of symptoms! I tested early and had positive tests for 5 days before losing the pregnancy :( I told myself I won't test until a week late this time to avoid heartbreak! Here I am only on cycle day 21 having all the same symptoms, went to the store to buy more prenatals and very nearly bought tests. it was hard to walk away and not buy them! if they are in my house I won't be able to resist the urge to test early!
