I am 13dpo today. For the last four days I have gotten positive pregnancy tests. They all have been super faint but definitely visible. They have not gotten darker though. It is starting to make me really nervous though. Unlike last time my Ob's office is being a little more sensitive. She said to take a test on Monday and if it is still really faint then come in for blood work. This weekend is going to go by really slowly. I have all my fingers crossed that I get a strong solid line on Monday.
