Okay, I've been ttc for 17 months, never once a bfp and have been pretty strict on my diet etc. for over a year BUT My birthday is this weekend and I have plans to turn up... i will be 7-10 dpo the whole weekend. Should I just not drink at all? My plan was to have one or two drinks when I went out and to test in the morning every day over the weekend in case I do get a bfp. I've heard you don't share blood with the embryo yet anyway and I would maybe just be at implantation this weekend IF we conceived (which has been a negative EVERY month for 17 months now) .... Thoughts?
