Hi marcy,
try the pregnancy test after you have missed your period.
I sometimes have a few days of spotting before my period starts. Some say it is normal as long as yopu dont stay spotting for weeks! ( but I was never on the pill so maybe ur situation is different than mine)
this could be;
1-implantation bleeding(ussually lasts 2 days)
2-normal ,since some girls spot before period,
3-or it could be progesterone defficiency since progesterone is needed to maintain the uteres lining, and when there is not enough progesterone, some blood is let out......
But then again I am no expert , I am just telling you what I have already read in books and on websites...Since I spot as well.
Anyway I hope I was of any help. U can go to google and type in "spotting before menstrualtion" and read as much as you can. But I stopped that since it got me all confused!
We have been trying for almost 9months and no luck and yes it is frustrating....But there is always hope.
Take care and good luck :)
