advice please!! update on vfl after

I misscarried 2 and a half weeks ago. Had emergency d&c and blood transfusion. Last week I took a test as the doctor said to check it was negative. I did two in a row first pee in the morning, both clearly negative. Today in the evening I have done a test and got a vfl?!!!!!!!!
I'm not getting my hopes up because surely it's too soon??? It would mean a positive test a week after conception? Going to test again in a few days. What do you think??
I have edited pic a bit was so faint hard to take a picture of x
*upade*
I have done 2 more tests today both positive still. I have contacted epu and they said test again end of the week, could be leftover hormones. Fingers crossed they get darker!!!
