Does this look like a chemical
Pregnancy? The top is 10dp <a href="https://glowing.com/glow-fertility-program">IUI</a> the middle is 11 and the bottom is 12. I would hope they would be darker considering the bottom one is 12dp and it is not to dark here is update photos from this morning 
The bottom is the most recent the line does not look darker from yesterday I getting so worried I still don't think I am pregnant I tell myself it is prob a chemical one or something
