Is there a chance that this is my rainbow ??

Starting from the beginning. I got my first positive on 9/11. So waited two days on 9/13 and got another positive which was darker than the test on 9/11. Well period was supposed to start on 9/14 but went and had my beta hcg and progesterone checked. Hcg was 102 and progesterone was 14. Went today for second beta and it rose to 305. Been through an ectopic and miscarriage in the past 3 years. So for everyone whose been through something similar does this lead to a good outcome?
