Implantation bleeding??

So on saturday or sunday I woke up and noticed a little bit of spotting. There was no cramping or anything and I didn't continue to bleed. My question is is could this have been implantation bleeding? If so, when can i test and get a positive result? I have done alot of research on the web but nothing really substancial and was just wondering if anyone had personally experienced it or known anyone or knew anything about it.

also, my periods are not regular, the last on that i had was may 12th i believe and that lasted about 3 days and was very weird. that was about 48 days after a period from progesterone withdraw to make suer i had estrogen in my system. before that it had been atleast a year since i had any kind of bleeding at all. I have been trying to get pregnant for a yr and half, nearing two years, and they think im not even ovulating but i cant be put on regular birth control with estrogen to regulate my periods and get me ovulating again because of my migraines. but because of the progesterone i could be randomly ovulating or whatever.

any answers would help! I also have an appointment with reproductive endocrenology on the 21st...

if your cycles are quite short 25-30 which is normal just at the shortest end you wont know the diffrence between a bleed caused by your progestrone lowering as your period comes or inplantation.
if you use basic body temptures your temp will still be high for a possible implantation bleed the nly thing you can do is sit tight and good luck.
