I was 10 days late. I had spotting last week once. I've had a terrible headache for a while now. I felt really tired recently. My flow was heavy but more so light. I'm wondering if this is implantation bleeding. I have one son. Not exactly sure I felt different last week. The headaches are abnormal for me. Took a pregnancy test before and it was negative. I had a sharp pain cramp yesterday. I haven't had cramps otherwise. #myfirstpost
