Was just wondering .. I wiped this morning and there was pinkish brownish light blood, but that's all there's been all day. My back has been horrendous like awful back cramping when I move. Has anyone experienced this with implantation bleeding before? I've never heard of back pain as a symptom but maybe it is. I miscarried 3 weeks ago so I can't go by period or anything to make anything clearer. Thanks x
