Asking for a friend, thanks in advance

My friend has done 2 hpt's. Both have like a extremely vvvf shadow, came up within time frame & is still there. I can see it slightly in person hard to pick up on phone. She is going to wait & retest soon as she's unsure of when her period was due (she stopped cerezette just over a month ago) asking for her if any1 can see it on pic it's difficult to capture as it is so very faint.
