Anyone who had implantation bleeding?

Its been 7 days since ovulation and when i went to the restroom last night i noticed a almost clear like brown almost not noticable but i look for that stuff and about a half cenimeter dot of blood. Does this sounds like it could be implantation bleeding? My period is due in 2 more days. As far as today theres been no more discharge like that, But im not having cramps...Is that odd? I heard that some have cramps like a period with implantation bleeding. Also idk if this means anything but ive been bloated for awhile now and having gas pains my nipples are also almost untouchable there so sore which ive never noticed before in my life. Thank you i just need oppinions because im TTC so before i start thinking maybe it happend this month i want some oppinions.
