I need help!

Okay, I've been TTC baby #1 for 18 months! I've been to the GP for checks and everything is normal... I'm on 71-86 day cycles and have had irregular periods for over 2 years. This cycle I caught my ovulation on it's very positive days which were cycle days 24&25. I'm now on cycle day 36 so I'm obviously nowhere near my period starting. I'm 11 or 12 DPO and did a pregnancy test earlier around 3PM (wasn't my FMU) and got a BFN. However, I've just go to the loo and when I wiped there was a pink blood, not a lot, could this be implantation bleeding even though I got a BFN and when can I test after this little bleed of it isn't a period?

Also, I've had very sore boobs and extremely emotional, which is highly unlikely.. and example of this is, I cried when my boyfriend sneezed and cried my eyes out earlier because I spilt my tea! Again, highly unlike me! I'm so confused and emotional!
