Came a few days before period was due. Day one brown, no blood, thought AF was on the way. day 2 spotting of red blood, no gloopy bits. day 3 back to brown. nothing since then. I normally have very heavy periods. I know it's probably wishful thinking but we have been TTC for a year and have had 2 miscarriages so am hoping for BFP christmas. When can i test? it was about 3-4 days ago?
