Please help!

Caitlin • TTC for 2 years since our early loss. I have 1 living child and 1 angel baby. My husband is the best. Praying for our rainbow!
I took a clear blue last night. Looked pretty negative. So later on before I went on and took the last one, knowing it would be negative so I could just wait on af (due tm) and I was positive! Faint but there. Now I took a new fr this morning and it's negative??? My heart is so hurt. Opinions would be great!
