So I tested yesterday BFN AF isn't due until tomorrow. I had cramping last night and some today and not like normal AF usually don have any until she arrives and such. Went to the bathroom a little bit ago and had some like brown blood when I wiped..could it be implantation? Or am I just being too hopeful ?
