I had it with my first pregnancy

When did it start? 6dpo and again at 10, 11 & 12dpo
What color was it? Brown
How long did you have it? Just once on the loo paper at 6dpo then one or two spots a day the other days
Did you have cramps/back pain? I felt like AF was on her way for 10, 11 & 12dpo so yes
Did you have any other symptoms with it? Not really, just felt like AF lingering. At 6dpo I felt fine though but spotting was awfully weird for me mid cycle

My BFP charts are linked in my sig so you can have a look (it was the Dec 2008 chart). I just tried to look but FF must be having issues. I think I remembered everything right though.

Good luck!
