@Jesspheebs Tbh it seems to me that line was behind the double taped dipping end of the strip and I think I also see another one not far away from it. IMO both too far from the control line to be a BFP, especially if they disappeared later. It's early days though, so good luck!
@Mummyofone1234, so exciting, 3 BFPs sounds very promising 
So I tested this morning and it was a BFN. With both my previous pregnancies, I had my first BFP at 9 DPO, which is today, so not feeling very hopeful atm
