Strong BFP got faint at night

Claudia

I’ve been taking an frer everyday since 10dpo when I got a vvfl. The lines has progressed beautifully, until now. I took an frer and clear blue digital today around 12ish. Got my strongest BFP and the digital came back positive. I don’t know why but I tested just now again. I’m honestly scared because I had a chemical two months ago. Which is why I test everyday. Except today I tested twice in a day. The first test was around 12pm. The second test was around 20 min ago 10pm and the line came back a little less strong. I have no cramps or am I spotting/bleeding. Should I be concerned? Has this happen to anyone else and had a healthy pregnancy?
