11 days late & pregnancy symptoms but BFN - why???

[mrscupcake]

I'm usually dead on 28 days on my cycle and on day 29 I had a very small amount of blood loss when I wiped and on day 30 another very small amount of brownish blood loss and that was it! I thought it could be implantation bleeding but all tests are BFN's. Were not trying but we've not been really careful either. I've been stressed quite a bit so thought it could be that but I'm now on day 39 and still nothing! Had cramps and back pain like I was going to come on 2 nights ago and then didn't. I'm so confused. Any ideas?!

Hmmm, very weird. If it isn't a BFP, stress and weight loss can cause that too. So your 10 days late?
