I am 13dpo AF is due tomorrow. I've been having moderate cramping, darkening nipples, bloating, constipation, lower back pain and extreme fatigue since about 6dpo I tested using FRER on 9,10,11&13dpo all BFN. If I spot the day before my period it's usually dark red like typical period blood but this looks pinkish. Is it possible to have IB at 13dpo? Is this even implantation blood ? I have so many questions... I feel super exhausted today, I can barely stand up for 10 minutes without wanting to pass out sleep . Has anyone had IB the day before AF and got a BFP ? Or am I out 😞
