Hi all, would just love to hear others experince. I took first response pt 4 days before af due and have got bfp although faint for 3 consecutive days. This morning I tested and it's even fainter and clear blue digital says not pregnant. Af not due until tomorrow according to glow which is cycle day 36. 18dpo. I'm guessing it's a chemical pregnancy. Would love some advice/others experince as feel so down today. Xxxxx
