Should I be concerned

Audrey

Over the last 2 days I have taken several test and all have been positive with good progression. I am currently 2 days from AF and this morning i noticed a pinkish/blood tint when i used the restroom and have had it every time sense then. My test this morning was also positive. I have suffered from two losses this year and I may just be overthinking us so I'm looking for opinions score for people who have had similar circumstances as I did not have any bleeding of any kind with either of my other two children. Any guidance would be greatly appreciated because I am not sure if this is a cause for concern or perfectly normal. I have attached photos if the test that I have taken over the last few days as well as a picture of the issue I am having. The pictures of the test I have taken are in chronological order starting with the first to the last I took this morning
