Anyone else experience implantation bleeding like this? Could it be...?

[JBOZ]

I've read so many things about implantation bleeding and pain i dont know what to think.. here are my symptoms!

I am about 4 days before my expected period. I have had some light brown discharge on and off for about 2 1/2 days now accompanied by some light cramps/ pulling sensation. Could this be implantation bleeding?

also..I have a very regular menstrual cycle and never spot like this

I am in the same boat. Usually if I spot before AF it is pink and the day before and the next morning I wake up with AF. I am cd24 and have a 28 day CY when on meds. However mine was just a little bit of brownish spotting this morning. I am hoping it is implantation, guess I will find out in a few days if that is what it was.
