Still holding on at 14dpo

I have decided I am not testing today. I know that most women know if they are preggers or not by 14dpo but I'm not sure if I would get an accurate result.
Some weird stuff has been happening, let me explain. On Monday (12dpo)& Tuesday (13dpo) I had cramping pains mostly all day, I even had this weir crampy feeling in my left leg, it was really uncomfortable. It felt like period pains, so I was suspecting that AF could be on her way. However my temps still remain high and I'm beginning to wonder if my thermometer is working - I get the same reading more or less everyday.

Yesterday I had some dark reddish and brownish discharge coming through, also when I wiped after using the loo it was pinkish the first time and more brownish subsequent times. I never usually experience spotting before my periods, I usually get full flow right away. After spending some time on google, I read that it could actually be implantation spotting from when the fertilised egg is burying into my lining. They say implantation can happen anytime between 6dpo and 12dpo, with the usual average being 9dpo. Could it be possible that I implanted really late about 12dpo and I had some implantation spotting yesterday. If this is the case, I wouldnt be worth me doing a Hpt until Saturday, which is 18 dpo. Actually FF has me down as AF starting on Saturday as I usually have long cycles with quite a long luteul phase.

If my AF comes before that, I will know that is is just spotting before AF comes, this is my first time on a clomid cycle, so this may be a side effect for me. As my temps are still up, I still have some hope that maybe I implanted late and I could still get a bfp. My breasts are still sore, but not as much as before, maybe the progesterone is slowly starting to decline.

Do any of you know of anybody who had a late implantation but still managed to get a bfp that lasted? I think I need some encouragement.

Later xx
