Help?! Confused?! (TMI warning)

Sarah
Sooo BFNs at 7/9/10DPO and a negative blood test at 10dpo- cramping was weirding me out. 
My period was due 26/6 but didn't come, glow then said 28/6 (today) I had what felt like AF cramps last night BUT there was a tiny spot of bright red, then brown. Nothing all day, and tonight a random small amt Vdark brown/black something. Wearing a Pad all day and I've not had to change anything. Add to this back ache, feeling sick this morning, feeling super tired...it was a long day at work but still worth the mention.
Have you had a BFN blood test, and still been pregnant?! I'm very confused and could use ANY comments :)
