I'm now 5dpo for the past couple of days I've had cramps. Today I started bleeding. Not lots but enough to have the wear a light pad. It is light but has now been going on all day and I still have cramps. AF not due for 10 days. O day was tested with Opk. I was feeling positive and cheerful this morning that it was implantation bleeding but now not sure. Has anyone else experienced this at all? Thank you, a worried TTCer
