I had a 5 day transfer on Monday 10th March. Today I started spotting and have period pains. I have had lots of twinges in the last few days which I hoped were implantation but now it's full on "dragging" pains low down 
I don't think AF is even due till the 19th!
Anyone had this and still got a BFP? I don't want to give up hope but need to feel mentally prepared for failure
