Hi there, has anyone experienced implantation bleeding that has lasted a few days to a week? I can't help but symptom spot in the two week wait. I am due on my period on Friday. Since 4dpo I had lower back pain which hasn't gone away. It's been a week now. I have also had light spotting every day for the last week. I'm not sure if this is implantation bleeding. Or something else. Anyone else had this and found they were pregnant? Thank you in advance.
