I’ve not had a period since late November, and I had some implantation bleeding right on schedule. I track everything I can, and I’ve got all the symptoms, right down to the start of morning sickness, and the headaches... this would be my second child, but tests are still negative!! I’ve missed two periods so far, and still no bfp. I have an appointment to confirm at the end of the month, but this feels so strange. Has anyone else gone weeks without a positive test even though you know you were pregnant?
