Decent BFP progression?

This is my first pregnancy. This morning I saw a very very very small pin head size amount of blood on my toilet paper after having a bowel movement (sorry TMI) and wasn't sure where the blood came from . I panicked and went and took another test (16 DPO test pictured here) since my period was due today and I was already nervous because I have had my normal pre AF acne. The line was much darker than the control line. I just wanted to be sure my progressions are looking normal and the dark dark line is a good thing. I did t have morning sickness as I have been so far this morning so I felt worried. As I type I now feel the gaggy feeling and the sickness coming on but I'm now over thinking everything. I have anxiety and worry easy about things. Especially about losing a baby I'm already in love with. Thanks for any positive vibes/insights/stories.
