Faint lines and chemical pregnancies

Ginger • Mom to a 2 year old boy. Baby on the way! Due September 7, 2019!

I had a chemical pregnancy in August and October. I had my progesterone tested and it’s normal. I am on vacation out of the country and I am 3 days late. I have taken the 3 pregnancy tests I have with me over the last three days. They were are all positive but very faint lines and today’s was even lighter. Anyone have really faint lines that varied that resulted in a successful pregnancy?
